Amazon has a Lexar 4TB drive, with heat sink, and supposedly 5% faster, for only $5 more:

I know the brand, but have never used their M.2 drives, any one use them?

Probably not for this price. 990 evo plus though should hit this price. Hoping it goes lower for BF tho 🤞

Don't we all 🙂. But in practice even the 990 pro uses a hybrid cache with it's DRAM. According to this benchmark (scroll down to sustained sequential write), it tracks about as well as the evo plus on sustained writes.

The p310 here seems to cache for longer, but then craters down to SATA SSD speeds 😐️.

According to that chart, it takes 60+ seconds worth of 6GB/s+ writing to 'crater' - that's over 350GB of sustained write.

That's a non issue for virtually every consumer PC/user, because that kind of sustained write just doesn't really happen in real world use aside from copying over from another fast NVMe drive (in non-enterprise/datacenter use - but even there, the need for that kind of sustained write is rare). ...and, if ever, how often do you really need to do that?
(That's also the 2TB drive tested in those charts - not sure if that would make any difference in a sustained test or not)

Fair point. In my case I would do it only once to clone a drive to this one. Most games aren't 350GB on initial download so that should be more than sufficient. Usually the cache size grows linearly with the drive size so the 4TB version should have a ~700GB cache size making any concerns there moot for sure.

Yes, but when it happens its a chore to wait for things to finish, esp bad over usb as it doesn't support hmb. They always leave out that test because it would take too long to benchmark

Sounds like this is personal experience. What was your use case for a 350GB file transfer from a source able to maintain 6GB/s?

As a photographer, even my CF Express cards only do 3.6GB/s max, though I seldom see more than 500MB/s sustained. It's never really bothered me because by the time I get all my batteries back in the chargers, lenses wiped, and bag mostly packed for the next day, file transfer is done. Curious how often you suffer this chore.

Stuff like backing up an entire boot drive before attempting to upgrade to windows 10 lts or 11. Shuffling off entire drives worth of data can be a chore.

Unless they actually use the drive. Almost all of that "SLC" is temporarily repurposed QLC. As the drive fills, the available cache shrinks. At 90% usage or above, the effective cache could be only a few gigabytes. Performance consistency (via acceptably fast native TLC/QLC write speeds and folding states) is the single most important metric for an SSD (and as pointed out above, often the least-captured from reviewers who think ten seconds of ATTO fully characterizes a drive). For casual to moderate users, the performance difference between any current SSD and another in an empty state is effectively noise.
