DRAM isn't used for caching user data in SSD. that's a misconception for people who has no idea how flash memory works.
DRAM was used for caching user data in HDD.

you are referring to the SLC caching, which is a controller function that all drive do nowadays.

DRam is used to temporarily store mapping data of which block of information is stored at which flash cell (because flash cell works better when multiple cells are written in parallel, but that means data are scattered around your entire drive). as you moving data around, that mapping has to be constantly updated. due to the faster speed, dram is a more desire medium for this job. when a ssd/nvme boots up, its mapping data is copied from flash cell to dram, and update to the drive data is done in the dram and then write into the flash.

for dramless drives, they make use of host memory buffer (HMB), so the mapping content is copied and manipulated in the host memory instead of on board memory. it could be an issue if you are on a OS that doesn't support HMB, but HMB is standard as of nvme 1.2.

in modern day OS like windows that support HMB, you are likely not going to find any meaningful difference between dram vs dramless drives in performance. any performance separation is due to the controller and flash themselves, not the dram portion.

dram is more important for Sata SSD, as there isn't a HMB like standard for SATA, updating the mapping data and rewrite of that information in flash not only reduce the drive performance, but also the cell life.

I don't think HMB works over USB, so if someone were to use a DRAMless drive in an external enclosure they will take a performance hit in certain scenarios.

Is this way better than Sammy's 990 Pro that's been plagued by drive disappearing in Windows or Bios, even after the firmware update with the magician?

The only real reasons for most consumers to actively look for a DRAM drive is if HMB isn't supported or if the drive is going to be used in an external enclosure. HMB is good enough for most systems.

Small caveat is that HMB supposedly works over Thunderbolt due to PCIe tunneling and should also be the case for USB4 NVMe enclosures in Thunderbolt ports and USB4 ports as long as the host device also supports PCIe tunneling via USB4.

Can anyone recommend a good inexpensive UsB c 3.2 gen 2 enclosure for nvme? Trying to troubleshoot whether it's one of my drives or the enclosure that is causing slow read/write

This blog includes a large range of m.2 enclosures, what chip-sets are in each, and a table comparing the chipset speeds and features.

If you're looking for a decent price per GB, you can get reputable brands for $100+ right now.

If you need the extra, mega, superduper premium performance for productivity use cases that require fast reads/writes, then sure, this might be what you're looking for, given the current market.

PS: Just spotted a similarly specced MSI Spatium M482 2TB for $109 + an extra 10% off ($98): https://us-store.msi.com/PC-Compo...Me-M.2-2TB

Price seems to have jumped up to $129.99. Crucial may look more attractive at this price point.

I got one of them this morning. Hoping with this drive it can extract files much faster than mine 3500 write speed ssd.

There's a 2tb TeamGroup deal right now for $110, also DRAMless

They advertise double the write speed at 7000 so it should!

Crucial T500 is the direct competitor to 990 Pro and sn850x. They should be indistinguishable in performance, aside from the issues.

I work at micron. And the industry as a whole are trying to increase prices back to 2-3 years ago. Micron along with sam&hynix was bleeding money with those deals from last year.

Last year's price cuts offered a better deal. $79 for 2TB if I recall correctly.

It was for $100 for comparable specs last year but you may be out of luck if you're hoping it'll go back down to that level this summer, possibly not for the year.
