i wonder when we will see good performance 4TBs for $200?
We already did, I bought mine for $239 https://www.ozbargain.com.au/node/794362
Unfortunately you've missed the boat, flash prices have risen dramatically over the past couple of years.
That is the exact drive I've been wanting.. Well guess I can dream
These had very high failure rate btw
Source: myself as a side hustle PC builder. I bought quite a bit when they looked really great value for the price and within the last year or so I've already have around 20% failure rate (the 1tb/2tb variants)
The price was almost that low not that long ago.
The industry is now making far less NAND than they have the capability to produce on purpose so they can make more money by selling limited stock at inflated ('stabilised' in corporate speak) prices.
They shot themselves in the foot by producing way too much in previous years and having to fire sale it, essentially, and have learned that the race to the bottom (price) isn't viable for them.
I don't see it changing anytime soon considering this is on purpose.
Thoughts on this for an external enclosure? Looking for a good performing 4TB drive to use with an enclosure if any one has any advice
Unless you have a PC with a Thunderbolt 5 port and an enclosure with a JHL9480 chipset the theoretical limit for transfer speed is generally about 4000Mbps, ie. if you've picked up one of those relatively-inexpensive ASM2464PD chipset USB4 ones from AliExpress, and that's ultimately closer to PCIe Gen 3 speeds - but it really depends what you're using it for, like is your workload heavy on sequential read/write activity or random 4K I/O? In its favour, this drive uses TLC and has pretty much the most power-efficient storage controller in the Gen 4 SSD space which is great to offset all the extra watts that ASM2464PD will burn (options for TLC drives in a 4TB capacity are also limited, and Micron are pretty trustworthy with a good warranty- unlike some others I could mention); overall it's a very good drive, however you could get away with a Gen 3 and/or much cheaper QLC drive if you're using this mainly for backups of low-value or infrequently-accessed data, eg. collecting Linux ISOs.
If you are thinking of using this NVME in an enclosure, get an Intel JHL7440 Thunderbolt 3/4 enclosure, slightly slower than the USB 4 (ASM2464PD) enclosures by only 150 - 200MB/s but runs cooler using less watts in both idle and in use. Plus Intel controller is more stable than the USB 4 (ASM2464PD) enclosures. I get 2840MB/s Read and Write using the Crucial T500 4TB in a Thunderbolt 3/4 Acasis TBU405 Air enclosure (No fan). If you are made of money and have a Thunderbolt 5 port, get a Thunderbolt 5 enclosure to get closer to the T500 advertised speeds but currently Thunderbolt 5 enclosures and docks are a big RIPOFF and seriously anything over 3000MB/s for 99.99% of the people is overkill.
Do you know any decent enclosures for sata? Or are they all much the same..
This 4TB model is a double sided package and not ideal for external enclosure. It will work, but it will run hotter than a single sided package, and won't last as long/may thermal throttle.
Too many false information here on the heat issue in an enclosure . Yes it is double sided but the NVME controller chip is on the top. The nand chips don't get hot, it's the controller that gets hot. Thus it can be cooled like every other NVME using heat pads on the controller side (top) or a heat sink directly bolted to the NVME if using directly in a desktop computer motherboard. Also by design the Crucial T500 runs a lot cooler than WD and Samsung high end NVME's so even a fan is not needed if using an Intel JHL7440 controller enclosure.
I didn't mean to spread false information. I was just talking generally on double sided packages, also there may be space constraints. I have no specific knowledge on the different enclosures. Just know double sided packages aren't ideal for laptops and PS5s so figured it would be the same in an external enclosure. Thanks for clearing up.
@BradH13: Plenty clearance even on double sided NVME's for almost all enclosures. I would only assume there might be clearance issues with ultra thin laptops that don't adhere to NVME design specs.
Gah, I just bought one of these this week!
At least I only spent ~$20 more… but still….
The T500 has a Missing DRAM Multiplexer, drops to ~150mb/s after the first few hundred GB, worse than dramless drives.

Get NM790 instead, that one only drops to ~2600mb/s and is much faster all round with higher endurance.

990 PRO drops to 1400mb/s and SN850X drops to 1600mb/s, so the NM790 is really quite good with the current pricing.
Tom's Hardware states the 4TB model does actually have the multiplexer, but it still has sluggish performance when you're absolutely smashing it with data, but it is better than the 2TB which you've linked.
https://cdn.mos.cms.futurecdn.net/HKjKGjLhzbogd4fdQPCngh-120…
That being said, they also say the fast cache is huge, and that you'll never experience the sluggish speed in real-world everyday usage.

Ah, good to know the 4TB version solves the multiplexer issue - unfortunately still looks like there are massive drops in TLC write mode (Crucial cost cutting…)
The SLC cache on the 4TB is big, but once the drive gets more utilized, cache recovery will become increasingly limited, especially with stuff being perma-saved onto the SLC. You really only get the full write cache on a completely blank drive.
For this price point this should not be an issue at all, it should be limited to the dramless without HMB tier drives (<$250).
Even the Team MP34 dosen't suffer from this issue @ $319, and the NM790 @ $365 is better in essentially every single metric.
Price is $409 btw
Thanks, updated to $401 (with the $8 code applied).
i wonder when we will see good performance 4TBs for $200? Maybe 2028?
Since the very first PCs, storage prices have been always gone down over time, but it seems in the last few years we are stuck in a market where prices have held.
