Possible Issue with SATA Controller

[Elks]

Hi Guys,

For the last couple months I've been running into some issues with one of my HDD. The drive is not performing correctly when it's plugged into my Desktop, when I've tried it in other computers it has worked fine. Here's a screenshot of the task manager during a HDD test.

The drive does not seem to settle on a consistent transfer rate. When I copied some data to this drive from another computer I was seeing a consistent 120 MB/s.

I have the SATA Controller in RAID mode with 2 SSDs in RAID 0. I've attached of a photo of these drives doing the same test, they seem to be performing as expected.

Do you guys have any suggestions for troubleshooting this issue?

Thanks

First you probably should run a test on it to see if there are any warning signs or problems:

If CrystalDiskInfo doesn't say anything is wrong with it, we can begin to troubleshoot the issue.

Have you tried connecting it to a different SATA slot to rule problems out there? Also, in the first screen shot it shows the disk at almost 100% usage. Is that how it always is, or is that just from you benchmarking it?
