Heavy Stuttering with Samsung 960EVO NVMe drive

[Miasmata]

I figure double posting is probably against the rules but this is a rather urgent matter - I have business I need to attend to and my computer has been out of commission for about a week now. If necessary I’ll take my problem elsewhere, where I might receive faster responses, no offense, but it’s quite a high priority problem, considering this has put me out of business for a whole week already.

Hi there Miasmata.

We are all volunteers and in different countries around the world I do understand it is urgent and we are trying our best to resolve your issue.

I will summon @Madmatt2006 as he is an Australian IT Tech. In the meantime, how much free space do you have on your C: drive? Low free space on the C:\ drive can and will cause slow read/write speeds, even to a SSD.

Also, is the drive connected via PCI-E or SATA? Did you also ensure the BIOS is up-to-date to ensure full compatibility with M.2 NVMe statistics?

Just because you bought a SSD drive, doesn’t mean a little work will not be necessary to achieve compatibility. This is the way of IT

[Miasmata]

The Samsung 960 EVO is an M.2 NVMe drive, connected directly to an M.2 port running at PCIe 3 x4. The BIOS is completely up to date.

Any updates for us?

Unfortunately, no - I’ve reinstalled Windows 10 on my Intel SATA SSD in the meantime, and am awaiting further ideas from forums, as I’m fresh out of ideas.

Hi Miasmata, I have a couple of Samsungs SSD’s although I’ve no experience yet with a m.2 drive. Something easy you could try which may narrow the diagnosis down is to put a live linux or another O/s on a DVD if you have a DVD drive, or if not put it on a flash drive and run your system off that just to check its not some other hardware issue. I know its not the same but its ever so easy to try and just might highlight the issue in something else other than the drive/driver.

I dont know but if you have an old sata hard drive and cable you could see if that works ok as well, you can download and use win 10 legally for free and again it may show an issue not related to your SSD. If you do this method remove the SSD first as 2 bootable drives are never a good mix?

[Miasmata]

Well running Windows 10 currently on my older Intel SATA SSD yields 0 problems whatsoever, so I’m led to believe it has something to do with the NVMe drive itself, or something software related like the NVMe controller.

[jmarket]

Believe what you will, was only a suggestion to narrow the problem down. Your call..

[Miasmata]

I just don’t see the difference between running Linux on a flash drive and Windows on a different drive. Does Linux even yet have support for NVMe?

[jmarket]

Yes. The latest Linux kernel supports NVMe and has been supported since kernel 3.3

Any updates for us?

I haven’t yet been able to come to a conclusion as to what the problem might be so I’ll be getting the 960 back on warranty and seeing if a new one perhaps doesn’t have the problem. At the very least my PC is running normally while the OS is installed on my Intel SSD, so I’ll get back to everyone once I have the 960 replaced.

Thanks for the update..
