P44pro Sequential writes are unusually slow

[alien]

 

Today, when I was copying a large number of files, I found that the writing speed of the p44pro was very slow.

Then I used CrystalDiskMark 8 to test it, and the sequential writing speed was only 2000MB/s.

I tried restarting and manually optimizing trim but it couldn't be solved.
I need help.

ps.Other ssd works fine, win11 23h2

Only a new firmware update can resolve this issue.

The same product, the SK hynix P41, was able to resolve the issue through a firmware update. 51060A20->51061A20

It's been years but Solidigm hasn't cared to fix the problem my p44 pro was thrown away, never produced Solidigm again. I've never seen a company that cares about the customer like Solidigm

Dear Champloo,

Thank you for your message.

Please note that while the SK hynix P41 and the Solidigm P44 Pro may appear similar, they are distinct products with different firmware, validation, and support paths. A firmware update for the P41 does not automatically apply to the P44 Pro.

Kind regards,
Gleb

Techpowerup did a writeup on this topic:

https://www.techpowerup.com/review/solidigm-p44-pro-2-tb-1-tb/6.html

~4000 MB/s SLC cache has limited capacity (apparently limited to ~300 GB total on the P44 Pro 2TB) and the drive can only write at that speed until the SLC cache becomes full. At that point the drive begins writing to much slower TLC flash at ~2000 MB/s.

When you do a test in Crystaldiskmark, there is no indicator to tell you how full your NVME SLC cache may currently be. That's why you can run 100 tests with different test sizes/ data types and get different write speed results.

It seems like ~2000 Mb/s sustained write speed is realistic for SEQ1M Q8T1 on this drive. You can expect burst speeds up to 4000 MB/s, but they could be infrequent depending on how frequently/ how much you're writing to your drive.
