The msi 482 is a dram-less drive using the PHISON E27T controller and Kioxia BiCS6 162-layer tlc nand. While there aren't any professional reviews for this exact model, it has the exact same hardware configuration (assuming no unreported silent revisions have occurred) as the Corsair MP600 Elite.

While the lack of dram means this drive falls somewhat behind true top tier gen 4 drives in real world performance (the heavily marketed peak sequential speeds are essentially meaningless in the vast majority of actual use cases), host memory buffer (hmb) mitigates the majority of the issues from a lack of dram. Its performance is overall good for most common use cases, and should be sufficient for use as a boot drive if you're on a tighter budget. This drive should not be used in an external enclosure, as hmb only works when the drive is directly connected to the computer through the m.2 slot. Likewise, the ps5 doesn't support hmb, so I generally recommend drives with dram for use in a playstation. If msi chose a similar slc cache configuration as corsair, then this drive will likely be somewhat slower than expected for enormous (50gb+) write operations. This drive supports hardware encryption, and should work with hardware bitlocker (using software bitlocker can drastically reduce drive performance). The endurance rating of this ssd is 1200tbw, which is fairly standard for a modern 2tb tlc drive, and comes with a 5 year warranty which is also industry standard.
Overall, while this drive at $90 doesn't match the truly incredible deals (such as the $90 2tb sn850x) from back when the ssd market was much better a year ago, it's a pretty good value considering the current market. It is worth noting that Black Friday / Cyber Monday are coming up very soon, and it's entirely possible there'll be better deals then, so it might not be a bad idea to wait if you don't have an urgent need for a ssd.
You appear to have a major misconception about the amount of system ram hmb utilizes. In most cases dram exists at a ratio of 1GB per 1TB capacity, which allows storage of mapping tables for the entire drive in addition to additional space for various caching functions. Hmb, on the other hand, typically utilizes less than 100MB of system memory as a substitute for dram. For example, the msi spatium m482 2tb (the drive in this deal) has a hmb cache size of 64MB, which is fairly negligible even on systems with only 8gb of ram: https://www.techpowerup.com/ssd-s...2-tb.d2199
Even though the hmb cache size is small, mapping tables for the vast majority of commonly accessed areas of the drive can be stored in system memory, therefore getting most of the primary benefits of dram without the increased costs. Performance will suffer in workloads involving many random access's for extremely large datasets, and overall performance will be lower due to additional overhead and reduced caching, but ultimately for most normal use cases hmb drives don't perform egregiously worse than drives with dram.
Also, regarding your statement about manufacturers "saving a few dimes", the cost reduction of foregoing dram is actually quite significant. Not only is dram (dynamic random access memory) many times more expensive per GB than nand flash, but it also generally requires a higher end and more expensive controller to go along with it, and adds additional complexity to the manufacturing process.
In conclusion, utilizing hmb with the drive in this deal will reduce available system ram by 64MB, not the 2GB you erroneously claimed. Please edit your original post to rectify your false claims and avoid spreading misinformation. In the future, please do some research before posting.

This seems like a decent deal if you need a decent 2tb ssd in the short term. This exact drive was $90 direct from msi for a single day a couple of weeks ago, and went frontpage at $100 ($10 more expensive than this deal) a couple of months ago: https://slickdeals.net/f/17724999-msi-2tb-spatium-m482-pcie-4-0-nvme-m-2-ssd-for-99-99-f-sThe msi 482 is a dram-less drive using the PHISON E27T controller and Kioxia BiCS6 162-layer tlc nand.

this is what I came sd for. Bravo if your name is not chatgpt
Before anyone asks, no, it doesn't have a DRAM cache. What do you expect for 90 bucks? This article[ign.com] claims that it's PS5 compatible, but it doesn't appear that they actually tested it.
PS5 just requires Gen4 drive, speed even at their lowest doesn't prevent using it.
Come on Black Friday/Cyber Monday dont let me down. I want a 4TB driver, not from a never before heard company who only sells on Amazon, TLC and falling into the $160-170 range. Dont need dram as long as it has hmb support I'm fine, it will simply be a game storage drive
Bought this for 100 a month ago with no sales tax which was nice, haven't bothered testing speeds but very satisfied with its performance as my boot/games drive.

Agreed I bought the Samsung pro 2tb on sale and it is great

A note on HMB. So the manufacturer saved a few dimes by forgoing adding 0.1% equivalent capacity of DRAM to the NAND flash, (e.g. 1GB DRAM for 1TB drive, 2GB DRAM for 2TB drive), you have to commit an equivalent amount of RAM in your system to compensate.

This means by simply installing a 2TB DRAMless drive in your Windows machine and turning on HMB, your system RAM usage increases by 2GB, your usable RAM decreases by 2GB. This 2GB cannot be swapped onto disk (that would be ironic if it can). This is especially important on low RAM systems (8GB). Your memory pressure will be much higher and you may experience slow downs because there is less available RAM to cache the file system and there is more swap happening.
You appear to have a major misconception about the amount of system ram hmb utilizes. In most cases dram exists at a ratio of 1GB per 1TB capacity, which allows storage of mapping tables for the entire drive in addition to additional space for various caching functions.
