What temps you getting, I have a SN850X 1TB as c:\ and its normally between 42-47C and its using the heatsink that came with the MB. Seems hot to me but its my first gen 4 drive.

I have 2tb and 1tb wd sn850. Using my MB heatsink and temps vary from high 30s to mid 40s. I wouldn't worry about your temps as WD rate them as a safe operating range from 0-85C

Thinking of buying a couple SN850X myself, worth buying the versions that come with heat spreaders from factory or not(4TB dont even have a option to buy one with a factory heat spreader on), also do we have to make like a 10%/20% over provision on these drives, i did on my old ssd drives, thx

If the price is good then yes.

If not then add a 3rd party Heatsink.

Ok cheers, do we need to make a over provision space, or was that only needed on older ssd drives, thx

I think the same rules still apply that the dram cache gets smaller as the drive fills up.

But given the drives are so fast anyway I don't think it's an issue.

Daytrader · 26 Feb 2023 at 15:45

Ok thx, i guess if we never fill up the drive, were all good anyway.

SN850X has firmware issues at the moment, a FW update is planned, no date given by WD.

WD SN850X NVMe SSD that beat Samsung, Seagate, and Hynix is BSODing and freezing Windows 11

The WD SN850X drive, which recently put up great performance against other NVMe SSDs like those from Samsung, Kingston, Hynix, Crucial, is found to be buggy in Windows 11 causing BSODs and freezes.

Is this only if the drive is the boot drive , have not noticed any issues with mine as a games drive.

mrk · 27 Feb 2023 at 18:00

It sounds that way!

StephenJ · 28 Feb 2023 at 18:16

My 850x has a new firmware in dashboard , version 624331WD

Muzzza · 28 Feb 2023 at 19:33

Kingston kc 3000 and wd sn850x 1tb x2 have all been fine. Gparted and macrium reflect free ftw.

Ran the SN850X 4TB as my boot drive for a few days before they pushed out the new firmware that seems to be the fix for the drive issues. Never had a problem with either firmware thankfully. New firmware is still fine, no errors in the event log, BSOD or performance issues. Rock solid drive so far.

Running on an Asus X570, 5800X3D and Windows 11, drive was cloned from my SN850 2TB.
