Enjoy!
I've seen a 980 pro fail giving BSOD, and 960 Evo fail, no longer detected. Both with minimal use. I'd welcome another make of drive with 5 year warranty.
Had the same thing happen to my 2tb 970 evo with only 6 months of minimal use. Bough from amazon us so samsung aus refused to help. Luckily amazon accepted the return
I have seen a 5 week old 980 pro fail, I was surprised as I always thought of them as premium drives and I usually deal with Crucial MX500 sata drives and have a very low failure rate.
All ssds can fail in the end, always back up important data because a warranty in the end will only replace the drive, not the data.
@JerraJones: All equipment can fail, and it's more likely to fail when it's either new or old. Many years ago new PCs from premium builders would include a certain amount of burn-in testing to make sure everything worked, but things were generally less reliable back then.
@macrocephalic: Yeah that's true but your gpu or cpu dying won't take all your data with it. Your psu dying in a spectacular fashion can fry some connected storage though.
Heatsink will help alot.
How did you go with Samsung warranty? Did Samsung RMA gave you at least the same SSDs? Samsung RMA used to offer model + storage upgrade for warranty. I got the latest model with double the storage size as a warranty replacement (brand new SSD). Not happy about the SSD died, but a better SSD eased the pain somewhat.
When i tried to look at comparisons i didnt realise that the link wasnt actually comparing the two exact products so dont mind me haha.
Also real world performance when you talk about comparing the two in boot time and loading times are only a fraction of a second faster. Its not like its "Twice as fast"
Read/Write times is one thing, but then there are also sustained read/writes.
In my functional use case in the PC, i probably wouldnt even notice the difference between the two. I was under the impression that the 970 evo had 1000TBW and this had 600TBW
That’s said what’s nore reliable for storage long term ssd nvme ssd or normal hdd 3.5”
It's easy to get excited with the quoted sequential read/write figures. In general usage, this SSD is not going to be 2X faster (it won't boot 2X faster nor load games 2X faster).
As for actually taking advantage of PCIe gen 4 x4 speed, can you name the scenarios or ways to achieve that? In folding write mode, 970 Evo Plus (current batch) is at the same speed as this SSD. In situations where DRAM SSDs shine, are you certain this DRAMless SSD can beat 970 Evo Plus?
For most people, this SSD will feel faster. Problem is, if you know the strengths and weaknesses of your SSDs, then you can expose the weaknesses of 1TB SSDs. I can pick one of my PCIe gen 3 x4 2TB SSDs and run a sustained write test to beat this 1TB SSD (because that 2TB PCIe gen 3 x4 SSD has a 900GB pSLC cache, 1TB SSDs, good luck beating that). You can imagine 2TB PCIe gen 4 x4 flagship class SSDs are also going to beat 1TB SSDs.
It seems you've jumped the gun and taken what I said out of context. To begin with, he (I'm assuming it's a he) was saying the 970 Evo was faster, not the 970 Evo plus.
It'd also be worth noting that I put a pretty clear disclaimer that said 'assuming it's as fast as advertised', it would be twice as fast. Obviously not at booting because most of your delay there isn't bottlenecked by your ssd. C'mon be realistic here… You'd hardly notice any difference between this ssd, 970 Evo/plus, nor any bottom of the barrel nvme in that regard.
The point of the message was actually to ask a genuine question - on what basis is it faster? A gen 3 with half the read/write speed is being compared to this model - I'm curious, is there something else I'm missing here?
@Dipaty: It is the 2x faster part which I think is too much marketing hype. My main point is PCIe gen 4 x4 SSDs pretty much cheat even more. The hyped up 6500MB/s is great to trick people, but in reality, since that causes folding write to happen for sure, and the folding write is not impressive at all, it is easy for people to get tricked.
As for the TBW side, TBW is quoted by manufacturer and YMTC's way to go about it is that since they are indicating higher TLC write cycles, they can provide less spare cells while quoting the higher TBW. Now, you be the judge on that. TLC is still TLC, some YMTC fanboys (p.s. not you) want to hype up TLC, but the reality is that TLC is still TLC, banking on the even if true better write cycle doesn't change the fact that it is still bounded by limitation of TLC.
600TBW for 1tb and 1200TBW for 2tb version.
so really comparing 600 vs 1000
I think the TBW will not be a problem for most ppl. 1000TBW is enough to write 274GB per day for 10 years. Should be good for PS5.
What's the eta for shipping?
This looks really good. $14 more than NV2 but double the speed.
TLC + HMB (No dram)
weakness from lack of DRAM can be mitigated with good optimised design. eg. WD SN770. no idea if this one has the good design though.
TLC is still superior with latency compared to QLC in general.
SN570, SN770 has a small portion of RAM on the controller to "trick" benchmark apps. In general usage, especially light usage, you cannot tell. In situations and use cases you can tell, those usage pattern are more work related so clearly work can fund a DRAM SSD.
In consistency tests or heavy / long mixed read/write tests, DRAMless SSDs do get exposed.
Judging by online reviews this is using YMTC nand which is really power efficient so it should be good for laptops too
Oh, so it's made in a new Chinese fab? I would be a bit concerned by that personally, trying to avoid Chinese silicon, especially as YMTC is on the US entity list.
well you should be OK because we're not the US
Which reviews did you read? I can't find any at all because this model is too new
Good deal, too bad I recently bought a 990 pro for $130. DRAMless though
seem too cheap? What's the catch?
No DRAM and uses YMTC nand which is technically sanctioned by the states which might make it cheaper?
only catch is if you want DRAM or use the DRAM on the computer …… DRAM prices haven't plummeted, might be demand from mobile phones as more DRAM in phones is a selling point but once you have 256 flash in a phone, how much more do you want from a marketing perspective ……
Good for Ps5?
Read/write speeds which suggest so.
Worth noting that ps5 doesn't support HMB so it's likely it will suffer performance loss in a ps5 when compared to a dram equipped ssd. Saying that will you notice it? Probably not…
Is that just when copying though? Or could a lack of DRAM hurt having performance too?
I'm no expert but from what I understand they do map data to the dram cache to enable faster reads. But as I said you probably won't notice it, especially with current gen games (nothing seems to make proper use of the fast ssd yet)
Also worth noting that the ps5's internal ssd is also dramless.
Source?
@evocable: Common sense. Given PS5 (console) uses shared memory for system RAM and GPU RAM, it doesn't make sense to put another 700MB DRAM for the SSD, not to mention PS5's CPU has a dedicated controller.
As for using DRAMless external SSDs on PS5, the DRAMless part is less of an issue compared to PC because on console, it is less likely you will be writing lots of small files. The real issue is DRAMless SSDs generally use inferior NAND. However, game developers don't really give a damn about SSD speed because you cannot squeeze out more fps with faster SSDs. Otherwise, let's all have 2GB Graphics card and PCIe gen 5 x4 SSDs.
Mixed read/write consistency issue on DRAMless SSDs, once again, not relevant to console gaming. Micro$oft's external CFExpress SSD solution currently use DRAMless SSDs.
Are there any test/reviews on this? Can't seem to find for this specific model
New model so questionable.
Reviews are here
https://post-m-smzdm-com.translate.goog/p/ad9803nn/?_x_tr_sl…
Lexar Ares is NM790 I believe, just different heatsink stickers
Can i upgrade this in a Dell G5 laptop?
if your laptop have a spare slot
Is that a heatsink or just a sticker than kinda looks like a heatsink?
Yes.
Technically the truth.
It's only a sticker.
If you want to use a heatsink then you'll need to buy a third party heatsink for this.
I need at least 2TB, will watch out for this model as according to Lexar site, a 2TB version of this model exists but can't find it for sale anywhere.
This is a new model.. only 1TB available in first batch at this moment. 2TB will be despatched from Lexar next month. Stay tuned
does it work with a NUC?
no reason why it would not mate
This or Samsung 970 Evo Plus
This over 970 EP, faster than 980 Pro in most workloads, and no widespread 0E issue so far
TiPlus7100 a comparable model reviewed here vs 980 Pro
https://post-smzdm-com.translate.goog/p/an33zxo3/?_x_tr_sl=z…
Is it just me or do these drives get hot super fast?
I put one in a case and wow it heats up to the point where its untouchable after 20mins of use
You'll need to use a third party heatsink since you're having heat issues. This NVMe SSD comes with no heatsink on it. The overheating may be killing the performance.
Some heatsink such as this will suffice.
https://www.pccasegear.com/products/39689/ek-m-2-nvme-heatsi…
Untouchable doesn't mean much, what're the actual temps?
Hot enough to not touch it, what is the temps these normally run at?
NVME SSDs start throttling at 80°C to protect themselves. In my experience, temperatures that fluctuate from 45°C to 65°C are pretty normal.
Get one of these .. Sure to bring your temps down ;)

got an error when checking out
Is that an error at the checkout screen?.
As i just got to the checkout screen just fine in the latest Firefox web browser.
Yep I get an "invalid formkey" and then it wipes my cart :(
If it still happens then try another web browser. The current browser may have a bug issue with the stores checkout system.
Yes. I got this error using Edge.
I thought Lexmark were venturing into the SSD business for a few moments there…
This is suspicious… Lexar's own website dosen't have it.
YMTC 232L TLC by Longsys/Lexar, +1
Ok to replace nv2 as boot drive or go with something more reputable? Nothing important on drive, just hassle to reinstall if it ever fails.
The NM790 is one tier below 990 Pro and P44 Pro, performance is roughly comparable with 980 Pro and SN850 BUT it's HMB DRAMless.
Maybe just get it anyway aye? need a bit more storage.
From many reviews Ive read, somehow these YMTC/Maxio 1602 based SSDs have fastest speed at 1TB capacity, then 2TB and after that the 512GB model. It shouldn't take long before the 2TB variant arrives, though 1TB is faster by 1% - 2%
@YRT: It's known that for PCIe gen 4 x4, latest gen 4 channels controllers can give 8 channels controllers some tough competition (since 8 channels really need 2TB to flex its muscle). It's true that based on most benchmark tests, Maxio 1602 based SSDs are hard to beat at 1GB (you pretty much have to use latest flagship SSDs). Problem is, 8 channel controllers shine at 2TB and the situation is different at 2TB. Annoyingly, WD is doing more tricks at 2TB (even for their 4 channels offerings), which can negate TiPlus7100's advantage. While I can understand Zhitai's reason for not cheating like crazy at 2TB, it just doesn't have the wow factor at 2TB.
I am somewhat interested trying out Lexar NM790 1TB, but mostly out of curiosity. It's annoying these are not available earlier. When cost effective YMTC 2TB SSDs (or equivalent) were being sold at $113 recently, it is hard to really get excited with this SSD. It might be great for 1TB, but my 2TB PCIe gen 4 x4 SSDs are still a tier above.
The 1TB SSD market is currently a big mess. We had 970 Evo Plus 1TB dropped to $69 (sold out) and other cheaper TLC SSDs at $59 previously. AU stock prices, not AliE or other Chinese sites (which could have even cheaper ones). NV2 1TB had some deals as well, but NV2 is honestly performed like a PCIe gen 3 x4 SSD with PCIe gen 4 x4 mode enabled.
If you love having cool figures in CrystalDiskMark for a 1TB SSD on PCIe gen 4 x4, then $79 is probably a good deal now. Warranty is through BPC. The SSD is a bit too new and it is doubtful people will get firmware updates for this later on.
And I just bought an SN570 1TB for the about same price…
It’s ok bruh, at least you enjoyed faster speeds a little bit earlier than now. There’s gonna be something new every time and for much less every now and then. It’s just the way the world works. #noRegrets
For those running a NAS, this could be a good scratch drive to use for transcoding etc.
Lexar being a bit tricky by listing PS5 compat for a HMB drive there in the specs.
Unless Sony have updated the firmware to support. (I'm guessing they're too lazy to do even a 64mb carveout because then they'd have to retest if things explode with even that much less free memory)
It's a Gen 4 NVMe SSD so it's compatible with the PS5. It's just that there will be slower than normal performance being a HMB drive since the PS5 doesn't support HMB. But i think the read performance will be ok. It's only writes that will suffer. But then again it's not as if it's going to be a problem if you're only downloading games to the drive from the internet.
While there are reasons to be cynical about this, being PS5 compatible, specs wise, is correct.
Basically, this is a new offering from Maxio MAP1602A with either YMTC’s 128L or 232L. YMTC fanboys on OZB would obviously state 232L. Unlike Phison E21 SSDs, MAP1602A seems to manage to utilise the PCIe gen 4 x4 bus fully, despite being a 4 channel controller. Even though the Chinese reviews are slightly biased (as they simply don't show you ANY test which have those SSDs not doing better, and cherry pick competition SSDs), the chosen benchmarks are still relevant to gamers and the cherry picked SSDs are decent enough ones.
No doubt this combination would be cheapest, actually PS5 compatible (in terms of meeting the sequential read speed) SSDs. The NAND technology is technically quite interesting and if it actually done correctly, it would be good. The main concern are (1) this revision of NAND supposedly corrected the reliability issue of the previous gen (and it is not long enough to actually state that's true yet) and (2) YMTC simply offered NO solution nor workaround to previous gen NAND issue. If there is issue discovered later on for this latest gen NAND, will YMTC do the same? To be fair, Samsung had the same issue with their planar TLC SSDs. Getting firmware updates for this SSD will be a big question mark. Maxio / JMicron isn't known for releasing firmware updates promptly. I had to gamble on a USB/NVMe enclosure firmware for my JMicron based enclosure (and it was a pain to find such firmware).
sold me a faulty motherboard dieing on my after a month then offered a store credit, had to go on 'Karen' mode about consumers law
So BPC's default warranty approach for this would probably be either a replacement unit (if BPC has stock) or store credit?
Even the one some people complained a lot - MSY, gave me a full refund for a faulty SSD. That's before UMart took over though.
Past experience on Centrecom, generally a long process with RMA, but eventually the wholesaler provided the refund (which Centrecom then provided to me). Took weeks though.
Did they end up refunding you once you went "Karen" mode?

I'd seriously think twice before click that 'Pay Now'
Just checking back in to report the PS5's quoted "read speed" on my one of this drive is 6272MB/s (and it's definitely compatible)
Run far from these folks and don't look back. I have a $3.5k computer sitting here from them that will not even POST. No responses to emails, no responses to ozbargain messages. Completely ghosting me while I sit here and work from home on my phone instead for the last 3 weeks.
that sucks man. I picked up a Local VIC click and collect of a 2.1k PC and it runs perfect. No issues and amazing cable management (plus free extra case fans).
I think shipping is what ruins this company + shit customer service unless you call them and can physically go to the store.

Well according to specs, assuming this performs as advertised (can't find any benchmarks yet) - it'd be almost twice as fast as the 970 evo…
So, on what basis are you saying that the 970 evos are better? Just curious.
BTW 970 evo 1tb has tbw of 600 and this one has tbw 1000
