LuckyL Posted October 17, 2019 Share Posted October 17, 2019 (edited) My NVME disc is feeling a bit slow and benchmarks confirm that depending on disc position, the performance is very uneven - this is both under Windows and Linux. It is the same when copying / reading from a RAM disc - can be fast, but also slow (< 500 MB/s). I updated to the latest firmware (12.3) but it has no effect on the speed (see screenshot) Any idea what could cause this? Should I return the drive? Specs: AMD Ryzen 3700X MSI B450A-Pro 32GB Ram Windows 10 64 Bit / Linix mint 19.2 64 Bit Edited October 17, 2019 by LuckyL Link to comment Share on other sites More sharing options...
Nazgul Posted October 18, 2019 Share Posted October 18, 2019 It may possibly be that the chipset cannot handle it or needs updating. I have a 960GB and speeds are pretty much on par with the specs. I used to have a SATA M.2 on my motherboard and it would do the 530MB/R and 560MB/W and when I put it in a M.2 USB 3.0 enclosure performance dropped by 50%, then I tried a 2nd and it was 410MB/R and 380MB/W, a big higher but it all depends on what controller. So, I decided to get a 3.1 Gen2 enclosure and now it's close to 500MB/R and W. And don't get me started on that horrible and crappy ASMedia controller. Don't know about AMD chipsets but see if they have drivers for it. Link to comment Share on other sites More sharing options...
LuckyL Posted October 18, 2019 Author Share Posted October 18, 2019 Thank you for your answer - I do however have the same issue under Windows (with latest AMD drivers) and Linux (no specific drivers install needed at all), so I think it is unrelated.
