Question SK hynix Platinum P41 2TB SSD Write speed dropped by half

Super Spartan · Feb 12, 2023

Only about 4TB written to the SSD so far, when I first got it, the performance was:

Now, the write has dropped by about half:

the only difference which I think was different is I was on Windows 11 21H1 when I benchmarked it the first time and now I am on the latest 22H2. The read speeds are the same. What gives?

PS: I even tried using the Samsung NVMe modded drive but that didn't change the write speeds.

I received my refund a long time ago.

Interesting but the other 2TB P41 I have never exhibited the problem. I still have it in my system and I have moved many TBs of data between it and my WD black sn850x. I currently have 1.8TB of games and other files on the drive and it is still giving me full read and write speeds.

Just avoid running CDM too much. With 4GB test size, it may write 40GB of data per run. That's about two days worth of writes and with the drive almost full, that's bad news for the limited write cycles of the drive.

For any affected parties, there is finally a firmware update that appears to address this issue available on the SK Hynix website. You must install the Easy Drive Manager to install the update.

https://ssd.skhynix.com/download/driver_manager/DriveManager-C3.2.0-windows-installer-x64.exe

Currently this is only available for the P41 Platinum. The P44 Pro variant does not yet have an update available.

Several people have installed the update and reported no change to their drive setup/data.

I was just going to comment on this. Need some more long term results.

Still, it's highly unlikely i'll ever buy another hynix ssd. It took them waaaaaaaaaaay too long to issue any kind of fix for this. Perhaps the driving force for this update was the cost of escalating refunds.
