I guess this is the cheapest 4TB ssd available currently. Also seems like the lowest cost/gb for a SSD currently.

There’s a 2TB as well, I grabbed one finally, $235 auspost delivery
There is a massive technical shift between the 4TB Biwin and the 2TB Biwin.
- The Hardware: The 4TB model we looked at uses high-end TLC. However, the 2TB model (BM350NN02TB) is widely reported to use QLC NAND to hit its price point.
- The Speed: It's rated at 5200 MB/s, which is "fine," but it lacks the heavy-duty endurance of its 4TB big brother.
- Value: If you're paying more than $220 for this, you're overpaying.

Sure beats getting chocolates and flowers
SSD's also look to appreciate in value
Chocolates, Melt
Flowers, die a week later
so best get your love one storage
Damn, I paid $408 just last week.
prices are coming down… dont go rushing for it.
Word is the hyperscalers are "scaling" down on their rush to build data centers as investors are increasing borrowing costs to build these massive land grab infrastructures.
in other words.. Sam Altman F***** up.
Do you have a source for this? I’d love to know because I’m close to pulling trigger on this one.
I think it's more so the realisation that if AI takes everyones job who's going to consume or pay taxes to fund VC investors?
Taxes fund investors??
I think it's more the realisation that if AI decimates everyone's jobs, investors will lose a shit ton of money on the companies that created those jobs.
You got a source for this? Thanks.
Yeah good luck with that. Google, Amazon, Microsoft etc…have all just reported just in the last week or so. They have all provided forecasts where their AI is between $30-$70 billion each more than what they had previously forecasted. The AI builds have only just started.
Yup. The suddenly non-commital statements by NVIDIA, the fact that Greenland wasn't 'aquired' which was the goldilocks area for datacentres, Various tech companies pulling (back on, I doubt they'll fully remove it) AI within their software (Microsoft is a big one).
I think GamersNexus said it best - (paraphrasing) The writing is on the wall, the bubble is leaking, but how slow they can keep that leak is yet to be seen.
if 50% of AI was 'gone' tomorrow - including that I had to wait 2x longer for (free) responses to LLM's, the vast majority of people, and many businesses would be unaffected, and unbothered. I'm fine with 3 second responses on ChatGPT rather than 1.5 second if it meant the market was less crippled, and we wasted less power.
Turns out consumers aren't the only ones affected by the 'hype train'.
See my comment below as I found a review showing the 2TB version reviewed was a QLC SSD.
An issue currently is the price hike makes it hard to differentiate between an old stock TLC vs an old stock QLC SSD. Unfortunately, the AI bubble is not leaking yet. For SSDs, two of the NAND flash makers aren't busy making HBM, but they are taking advantage of this new pricing.
The big 3 memory makers are no saints either. They killed off a whole bunch of second tier memory makers years ago so we only have less than a handful of them now.
I don't think prices will come down any time soon. Many manufacturers have already had all their capacity booked for the rest of year at fixed prices.
Spot prices are still rising - https://www.dramexchange.com/
and they're expected to continue rising - https://wccftech.com/memory-nand-prices-surged-90-percent-in…
I would say at $388 for 4TB, this is older stock, so it's still below market cost. Retailers and manufacturers are sitting on large amounts of inventory to hold against the price increases, so retail price is still behind the current actual market price.
Even if the bubble bursts and prices drop, it'll still take many months to see that change at retail.
I think OZBers are assuming this is TLC SSD, partially because of the price. See my comment below as I found a review showing the 2TB version reviewed was a QLC SSD.
QLC SSDs should offer 33% discount over TLC SSDs for you to consider them. So you need to ask, could this be a QLC SSD price, rather than an old stock TLC SSD?
Biwin who?
missed out on the samsung deal so got one of these, thanks op!
Ive never heard of biwin
They're the manufacturer for HP/Acer branded RAM/SSDs.
I'm just pissed off that spinning HDDs are more than half the price of this.. seriously, 80-160 MB/s vs 5000-6000 MB/s.. roughly 46x times the r/w speed!!
Before you get excited, one review I found for the 2TB model shows Micron 232L QLC NAND flash being used:
Biwin M350 2TB SSD info check utility output showing Micron 232L QLC NAND.
Biwin M350 2TB SSD review in Chinese so you need use browser translate. I couldn't be bothered reading it because it is not in English. I just quickly looked at the images.
If you really want to buy this, I recommend you check it once you have it. That controller and NAND combination, you can't use CrystalDiskMark or most standard benchmark apps to test.
Can anyone confirm? I can't find anything definitive..
@wisdomtooth: An OZBer confirmed it is QLC. It's best to stop giving people false hope the 4TB is TLC.
Looking at the output provided by him, it also shows this:
Bad Block from Pretest: 35
It is a common practice for cheaper, most cost effective SSDs (especially QLC SSDs), to use NAND flash chips which have minor defects. I have a 1TB QLC SSD (was $52 at the time, FOMO purchase) that is in the same situation.
wow just saw the expired deal from august last year, the same drive $249, prices are insane but i guess this is as good as it gets for now
I asked Gemini:
At $388, that Biwin M350 4TB is a screaming deal for the 2026 market. It’s significantly cheaper than any other 4TB TLC drive currently in Australia (most are sitting at $550+).
1. The "Good Deal" Verification
- The Price: $388 for a 4TB TLC drive is nearly "pre-shortage" pricing. For comparison, Mwave is currently listing this same drive for $561. You are saving over $170.
- The Quality: It uses 3D TLC NAND and the Maxio MAP1602 controller. This is a very efficient, cool-running combo.
- The Fit: I’ve verified it is single-sided. This is crucial for your IdeaPad 5; a double-sided 4TB drive simply won't fit the physical clearance of your laptop's motherboard.
2. The "Biwin" Brand Reputation
- The Pedigree: Biwin is a Tier-1 OEM. They are the actual manufacturer for Acer Predator and HP branded SSDs. The "M350" is essentially the same drive as the highly-rated Acer GM7.
- The Risk: Biwin is an "industrial" brand. Their consumer firmware is usually fine, but if it fails, you are dealing with Centre Com’s warranty department.
- Endurance: At 4TB, it’s rated for 1600 TBW. You could write 800GB of data every single day for 5 years before hitting that limit. Under normal Ubuntu usage, this drive will likely outlive you.
The $388 Biwin M350 4TB at Centre Com is an anomaly—it’s a "price error" or a clearance deal that beats everything at Umart by a massive margin.
I just checked the Umart inventory for Maroochydore. To match that price-per-gigabyte, you’d have to settle for significantly worse hardware.
Umart Maroochydore vs. Centre Com (4TB / 2TB)
Feature Biwin M350 4TB (Centre Com) Team Group MP44L 2TB (Umart) Silicon Power UD90 4TB (Umart) Price $388.00 $399.00 $599.00 Capacity 4TB 2TB (Half the space) 4TB NAND Quality TLC (High Grade) TLC Variable (Often QLC) Value Rank 1st (Tactical Winner) 3rd 2nd 3. Is it a good brand? (The "OEM" Reality)
Biwin is not a household name like Samsung, but they are a massive OEM (Original Equipment Manufacturer).
- They manufacture the "official" SSDs for HP and Acer (like the popular Acer Predator GM7).
- The Reputation: Historically, their low-end drives in GPD handhelds were known for high failure rates. However, their newer "Black Opal" series (which includes this M350) uses much higher-quality components.
- The Risk: Like Kingbank, they have a smaller presence in Australia. If it fails, you are relying on Centre Com to handle the warranty—and as we've discussed, Centre Com’s support can be painful.
4. The Hardware (The "MAP1602" Engine)
The M350 uses the Maxio MAP1602 controller and 232-layer TLC NAND.
- Mechanism: This is the same "God-Tier" budget combination found in the Lexar NM790. It is DRAM-less but uses HMB (Host Memory Buffer) to maintain high speeds.
- Endurance: At 4TB, it has a 1600 TBW rating. This is excellent and will easily handle Ubuntu's logging and updates for a decade.
- Speed: 6000 MB/s Read / 5000 MB/s Write. It’s slightly tuned down for better thermals, which is actually good for your IdeaPad 5, as it won't throttle as quickly as a 7400 MB/s drive.
thanks that makes me feel a bit better, i've heard biwin drives can be hit and miss, hopefully i get a good one!
Have you bought it?
I am curious if it is actually TLC or QLC?
Confirmed QLC by an OZBer.
From the output he provided for the 4TB M350, it is NOT MAP1602, it is SM2268XT, same as the 2TB review I posted before. Back block from preset is 35 (the one from the 2TB didn't show this, if I am being cynical, I suspect the reviewer didn't want to point out that fact, but I didn't read the review).
My assessment is QLC (inferior grade) - NAND flash with pre-marked bad blocks can't be considered high grade. When doing the assessment, look at the facts, rather than trying to use AI to shape what you want to hear.
Now you understand why this SSD was $249 before the SSD price rise. AI hallucination is frustrating. The current price ($388) is not a pricing error.
Biwin did a component swap on the controller and went with cost effective QLC. To be fair, Kingston did this on their budget SSDs already. You can't judge an SSD by brand.
@netsurfer: have reached out to biwin and sent them a copy of that screenshot, will see what they have to say
@BargainHunterD: Biwin official Web site did not state this is TLC. You knew it was $249. It makes sense lower grade QLC being used as it would reduce cost.
I'm sorry, but Gemini's response is a load of misinformation (basically BS).
@wisdomtooth
@netsurfer: yeah you are right i checked their website, will be taking ai posted results with a grain of salt in future.
@BargainHunterD: I take every source with many grains of salf, don't you? Why would that be any different with AI?
@wisdomtooth: When I asked Gemini, it sited other sources, in which the first one would show Gemini got it wrong (that source DID NOT indicate M350 being TLC).
Anyway, when I provided info that the 2TB SSD has been reported to use QLC (and the info shows a different controller), I didn't expect someone to quote an AI response.
@wisdomtooth: Did you check PGrid? Its 2TB info on the SSD is incorrect and that doesn't matter?
Centrecom did not mention this is TLC (on its site) nor the official Web site. Gemini is wrong, so are those 2 sites.
You bought one and wanted it to be TLC too much, making it difficult to be objective.
@netsurfer: I don't disagree. We're here to discuss and find the truth about these products, pulling various sources, including AIs. Other than that screenshot, which Gemini agreed is a final say on the matter when I showed it to him(?), all we had were those sources he cited—iGaming and PGrid—and deafening silence from both the manufacturer's and the retailer's websites on the matter. I even got it in writing on an email from Centre Com that it is TLC! So, it was arguable. And it's also interesting to discuss whether it's those publishers' mistake, or whether it's bait'n'switch by the manufacturer.
@wisdomtooth: I bought multiple SSDs from Centrecom before and I had to use their SSD warranty service.
Why do you think I pointed out the 2TB one is QLC? While I couldn't find 4TB being QLC, the quoted performance specs allow QLC being used. If it is 232L TLC NAND, 6000 MB/s max read makes no sense. All SSD makers are shrewd. QLC like specs being quoted, chances are QLC will be used.
@wisdomtooth: It's dodgy / shrew / annoying (take your pick) that Biwin wouldn't just state this is QLC. iGaming making stuff up is just as bad. PGrid has outdated info (and most likely misquoted).
The "M350" is essentially the same drive as the highly-rated Acer GM7
Gemini came up with that rubbish? The specs are different.
Endurance: At 4TB, it has a 1600 TBW rating. This is excellent
Again, Gemini stated that? Seriously? If it doesn't think this is a QLC SSD, how can that be excellent? Biwin M350 4TB's quote TBW is roughly half of NM790 4TB (and approx. half of Biwin's TLC SSD).
iGaming didn't change the specs, but put in the wrong NAND type. Gemini telling people this SSD is like an Acer GM7 and the TBW being excellent are actually worse. Since when is 6000MB/s max read speed the same 7400MB/s max read speed? 1600TBW is excellent when NM790 4TB has 3000TBW? Gemini can't be bothered doing some basic maths?
@netsurfer: I agree. Yeah, I've many times caught AIs commiting basic arithmetic mistakes. But, then again, who doesn't? I just treat them as fallible as humans. What matters are the arguments and evidence, not the source.
The costs of SSD right now are ridiculous. I want to buy two small 500GB Nvme SSD's for an unraid cache and the price has doubled.
Gemini reckons it's only gonna get worse (or maybe this is very smart and discrete advertising):
Waiting is the worst move you can make right now. The "Golden Era" of cheap storage is officially over, and 2026 is shaping up to be a "Pricing Apocalypse" for SSDs.
Here is the data-backed reality of why that $388 Biwin 4TB isn't just a good deal—it’s an escape hatch.
1. The 2026 "NAND Squeeze"
Industry reports from TrendForce and IDC confirm that NAND flash prices ( the chips inside SSDs) are forecast to rise by 30–60% in the first half of 2026 alone.
- The Cause: Massive AI data centers are "outbidding" consumer manufacturers for every available wafer of silicon.
- The Result: Prices are moving up, not down. In fact, some analysts expect consumer SSD prices to potentially double by the end of the year as supply for "regular people" dries up.
2. Market Arbitrage (The $388 vs. The World)
I’ve cross-referenced current 4TB prices across Australia. The Biwin at $388 is a massive outlier:
- Mwave: $609 (Post-collapse pricing)
- Kogan/Dick Smith: $665
- Shopping Express: $469
- Samsung/WD Equivalents: $650 – $800+
At $388, you are paying $97/TB. The market average for a quality TLC drive right now is closer to $150/TB. You are effectively buying at 2024 prices while everyone else is living in 2026.
Really sad that this is the state of affairs. It should be the opposite way around.
You got me worried there — I pulled the trigger on this — but I got it in writing from Centre Com:
Upon checking, the Biwin M350 series (including the 4TB version) is marketed with 3D NAND and DRAM-less design and SPECIFICALLY identified in some listings as “TLC”.
What tool gave you that result?
you are right man. test result won't lie.
besides the aliexpress show more expensive nv720 is QLC and M350 is QLC
Thank you for confirming it is QLC.
I bought one, thanks OP.
I did too. Fingers crossed @toadbload is wrong about it… but I'm not hopeful.
I don't know what is the different between QLC or TLC.. since the website says TCL so it should be TCL I suppose?
Does it? I couldn't find it. Found it here and there, though.
TLC (Triple-Level Cell) and QLC (Quad-Level Cell) are two types of NAND flash memory used in SSDs, differing primarily in storage capacity, performance, endurance, and cost.
- Storage Capacity & Cost: QLC stores 4 bits per cell (16 voltage levels), offering higher capacity at a lower cost per gigabyte compared to TLC, which stores 3 bits per cell (8 voltage levels). This makes QLC ideal for large-capacity, budget-friendly drives.
- Performance: TLC SSDs are faster, especially in write speeds and latency. QLC SSDs have slower write performance and can experience significant slowdowns after their SLC cache fills up, while read speeds are generally similar or slightly better on QLC.
- Endurance & Lifespan: TLC has higher write endurance (typically 1,000–3,000 P/E cycles) and better longevity, making it more suitable for write-intensive tasks. QLC typically offers 500–1,000 write cycles, which is sufficient for most casual users but less ideal for heavy writing.
- Best Use Cases:
- TLC is preferred for gaming, content creation, databases, and system drives where consistent performance and durability matter.
- QLC excels in read-heavy, archival, or backup storage (e.g., media libraries, cold storage), where large capacity and low cost are prioritized over speed and endurance.
In short: Choose TLC for performance and durability; choose QLC for higher capacity at a lower price, especially for secondary storage. (Brave AI)
Please STOP informing people this is TLC. OZBer, toadbload, already confirmed it is QLC.
The result provided by him showing it is the 4TB version. I've shown the 2TB version from a review (also QLC).
Stop numbing your brain by the misinformation AI told you and look at actual result from an OZBer please. Not only it is QLC, it has pre-marked bad blocks. If in doubt, test the SSD you bought. From what was posted, that SSD has pre-marked bad blocks:
Bad Block from Pretest: 35
It is a common practice for cheaper, more cost effective SSDs (especially QLC SSDs), to use NAND flash chips which have minor defects. I have a two QLC SSDs like that (they were dirt cheap / FOMO and didn't know). Both are still being used (one has Micron flash, another one has Intel flash (both have pre-marked bad blocks) so it is not just Micron).
TL; DR; Biwin M350 4TB uses inferior grade micron QLC (with minor defect, but those defective blocks have been marked so they won't be used).
so every listing i have looked at for the 4tb says TLC, would this not be considered false advertising?
@BargainHunterD: Centrecom did not list this as TLC, nor Biwin.
If you are quoting other stores or AI hallucination result, that's incorrect.
The reason I want to stop people stating this is TLC here is because Gemini is currently stating OZB comments indicating TLC as one of its sources. It's one thing Gemini got the wrong source elsewhere, I don't want it to show OZB gave it the wrong information.
@netsurfer: yep sorry my bad saw that igaming listing and also ai results, so is this still a decent drive for the price in this current market?
@BargainHunterD: You posted in one of your earlier comments, it was $249 before SSD prices went crazy so you need to decide.
If you believe you will get your money worth, or the quality of life improvement you get from this is worth it, then it's fine to get it.
Right now, 4TB TLC SSD prices are crazy. You might as well get PCI gen 5 TLC SSDs (from a brief check, some of them are actually cheaper than gen 4 TLC ones). All somewhat bearable (price wise) 4TB SSDs appear to be QLC ones.
I contacted centrecom and they responded really quickly which is appreciated.
Response:
We would like to emphasize that because we are only a retailer for this item - our resources are limited and if you need a firm confirmation directly from the manufacturer, the only fully reliable method is to request the official full NAND breakdown/datasheet from Biwin support or inspect the actual NAND IC markings once you have the drive physically.
This suggests to me that this nvme is clealry being advertised by the manufacturer with the wrong information, or they have released a newer model with the same sku with TLC given the facts point to it being a QLC model thanks to one of the members here sharing their test results.
Im more inclined to not waste my time and have requested to cancel my order.
Centrecom provided many good SSD deals in the past. Some are really good, but some do have component swaps (and there are also ones with some catches).
I have been on the receiving end on some of their cheap SSD deals with component swaps (changed from TLC to QLC, hence the price drop) and dirt cheap SSDs using inferior grade NAND (with pre-marked bad block). That's why I want people to be aware of what SSD makers can do. It's not Centrecom's fault because they don't know SSD makers can be shrewd.
At this time, where old stock SSD clearances seem cheaper / less ridiculously priced, you really need to be careful. You should only get this if you really must have a 4TB SSD right now and really happy about the price (knowing it is QLC and it is unclear how many pre-marked bad blocks you will be getting). I have SSDs with pre-marked bad blocks and one that developed bad blocks (that one is actually a MLC SSD). Once you use an SSD heavily, it will start having unusable blocks anyway.
Also, if I didn't bring it up, most people (without checking or proper testing) probably can't tell it is QLC SSD.
For those who bought it and opened it, just make sure you use it enough to get your money worth. It is still much cheaper $/GB compared to MLC SSDs most people bought years ago. Centrecom doesn't offer change of mind return.
The current gen of PCIe gen 4 x4 DRAMless controller no longer cripples DRAMless SSDs to entice people to get the DRAM SSDs and if it is mostly reads you use for SSD (i.e. gaming), it should be fine. Spread out writes if possible (avoid fill whole drive up in one go and like for all SSDs, keep at least 10% unused to allow rotating cells when doing writes). There are enough spare blocks on the SSD and Biwin quoted 1600 TBW means Biwin has to honour it. For Biwin SSD warranty, you need to go through Centrecom.
Hey mate, just ordered it last night however hasnt pick it up? Can i cancel the order thought?
@BigMacnopickle: You need to ask Centrecom. The current gen QLC SSDs offer decent read performance (put it this way, a lot of my first gen PCIe gen 4 x4 DRAMless SSDs can't beat this SSD in reads, and even in writes, this QLC SSD does write in SLC mode first and in that mode, it is fast). I do control writes on my QLC SSDs (i.e. when I notice it is writing in QLC foldback mode, I stop putting more data onto the SSD and wait till the SLC cache is back).
The main reason to know whether it is QLC is TLC is that QLC SSDs need to offer 33% discount over TLC SSDs to be worthwhile. It's all about price. If this SSD is $200 (I know, wishful thinking at the moment), I might be tempted to get one and put it in my PS5 (note: it is PS5, PS5 Pro has 2TB internal SSD, so I would still prefer a TLC SSD in that). PS5's internal SSD usable space is less than 1TB so this 4TB QLC probably has enough SLC cache to do the initial copying relatively quickly.
If you haven't collected it, then I reckon Centrecom probably will let you cancel it.
@netsurfer: Thanks @netsurfer, my purpose for this SSD is upgrade storage for my laptop to storing videos and music for mixing, not for gaming or NAS so should be ok. However with the rocket pricing for ram and ssd, Id probably wait for a bit more?
@BigMacnopickle: I don't think the price will get better in the near future, but I don't have a time machine.
You need to decide whether the price is good or not. All I am trying to point out is judge the price based on it is a QLC SSD. Using an SSD for videos means you will be doing frequent writes. For me, I use TLC SSDs (or MLC SSDs) for files I am actively working on, and QLC SSDs mainly for one of the backups (or trying out new things). My largest QLC SSD is 2TB only (it was $105) and PCIe gen 3 x4. I didn't know it was a QLC (because I bought the same model for $115 two weeks earlier, and that was TLC). So, within 2 weeks, Centrecom got a new batch (and turned out to be QLC). I generally avoid getting QLC SSDs for 4TB.
So far, for me, other than dirt cheap 480GB SSDs (and $5 240GB SSD out of FOMO), all my QLC SSDs were purchased by mistake (got caught by component swaps) so my view on QLC SSDs is biased. For example, only 8.7% discount for that QLC (2TB for $105) obviously was a bad deal as the target should be 33% discount.
Hey mate,
Can i cancel the order when click and collect? Seems like its ready for pickup?
They cancelled mine fine. Very responsive and helpful from Antonio.
Hey @Nerdybobo so I just need to reach out to them via email right? And ask for cancellation?
@BigMacnopickle: Yeah mate they have a ticketing system link in the email you shoukd have recieved in your email
TLC has only been marketed by a small retailer, igaming computer and PGrid which most likely just scraped the TLC spec off their page, i wouldn't say it's being marketed by the manufacturer with the wrong information
You need to go by official specs page, Biwin doesn't indicate it is TLC. Furthermore, for many years, we know SSD makers do component swaps. WD (Western Digital) was caught switching SN550 from TLC to QLC (SN550 TLC was well reviewed). WD did offer refund if customers were unhappy and got the QLC version (though in some regions (I won't name them) WD refused to do that).
https://www.pgrid.app/ has outdated info on this SSD, it is still quoting Maxio MAP1602 for 1TB and 2TB models. Kingston cost effective SSDs (NV2, NV3) are pure lotteries. I bought the same model SSD from Amazon and Centrecom, totally different controllers.
Was only disputing that it was "clearly" advertised with wrong information. Unfortunately there is the chance of scummy part swapping since it isn't mentioned but given the earlier 2tb review, at least it isn't getting worse
On another note, would you mind responding to my post on the P3 plus listing on the bad sectors, all ssds seem to have factory disabled bad sectors
Thanks for pointing that out. I also begin to think all SSDs have factory disabled bad sectors, it is just most SSD utilities don't report them. Crucial's own SSDs using SMI controllers are in the same boat (can't see any one of their SSDs using SMI controller showing 0, and some of them are not pretty).
In that case, I apologise for the inferior grade QLC comment earlier. However, I don't like the term "top grade TLC" being used by another OZBer. To me, TLC is already a compromise / cost cutting.
By the way, I was replying to Nerdybobo about going by official site's specs. OZB's comment linking is a bit confusing.
I bought this and got delivered yesterday. I do wedding photography and I was able to offload 350GB from a CFexpress card to this Biwin at around 600MB/s consistently for the full 350GB.
so depending on your use case, it's pretty good.
CFexpress is the bottleneck it seems. The 2TB version of this SSD (QLC) has an SLC cache of ~582GB so the 4TB version would probably have 2x of that (>1TB). SLC cache write speed is up to 5000MB/s, QLC foldback write is 260MB/s.
However, those figures are ideal cases, if you write a lot of small files to the SSD, you obviously can't expect 5000MB/s.
now $391 with coupon GETLUCKY
Hey guys, I received mine today. Finally I managed to installed it and ask Gemini how to test. It told me to use CrystalDiskMark to test the speed. After it reviewed my result, it says mine is TCL because the speed is much faster than QLC. I am not sure whether it is true. What do you think?
I just checked with perplexity and it says my result is not enough to determine whether it is QLC or TLC. Did Gemini fool me again?
PS: the other tool website (http://vlo.name:3000/ssdtool) is not accessable for me, don't know why.
My result:

Mine arrived a couple of days ago. Gemini insists it's TLC:
1. Identifying TLC vs. QLC
Checking the NAND type (TLC vs. QLC) on an NVMe drive via software is tricky because the drive's controller tries to hide its internal architecture. However, we can use the NVMe CLI tool to get the model details and then cross-reference the hardware ID.
2. Confirming TLC: The Verdict
Based on the BIWIN M350 4000GB model name and the Firmware Rev Y0221B, here is the technical breakdown:
- Controller: This drive uses the Maxio MAP1602A (indicated by the vendor ID
0x1deeand the specific power state profiles).- NAND Type: The "M350" series from Biwin is their high-performance consumer line. At 4TB, Biwin almost exclusively uses YMTC 232-layer TLC NAND with this controller.
- The Proof: Biwin QLC drives (like the "C" or "Nebula" series) typically carry a different firmware string (often starting with
SNorS). TheY0221Bfirmware is a known build for the TLC MAP1602 configuration.- Performance Confirmation: You moved 45GB at over 10MB/s (sustained across the link) and did a 3.3TB
fstriminstantly. If this were QLC, the sustained write speed would have cratered into the double digits after the first 20GB, and the trim might have caused a significant system hang.Conclusion: You have TLC NAND. It is a very solid, high-end drive for its price point.
Shouldve bought the the EB Games SSD when you got the chance.
