Hello, recently I noticed one of my SSD's seemed to be intermittently reading/not-reading, and generally acting like a dying drive.
I loaded it into linux and found the drive was running extremely slow, so I slowly backed everything up from that onto a USB external drive.
After backing up, I disconnected the SSD drive I assumed was dying (was connected via sata), and connected two brand new SSD's (via sata), and then formatted them together in windows as a software raid drive (striped).
I fired up crystal disk benchmark tool and found that the first reading showed the expected 1GBps speed, but each consecutive test after the first, the speed drops very low, until on the last test it shows an average of 35MBps.
I tried copying files from a USB-drive to this raid drive, and got an average of only 35MBps fluctuating between 35-135Mbps. Tried copying from another SSD to this drive and got the same average.
Copying between two USB drives shows normal expected transfer speeds.
When I look at the performance tab in task manager, I see that when the SSD's are having files transferred between them, the usage % is on average around 3-5% with a max of 25%. Transferring between the USB drives shows near 100% usage, with normal expected speeds. (see screenshots)
SMART info shows no problems except that it says one SSD is running quite hot when it should not be. (mounted outside case, and not under extreme loads) I can feel the SSD and it is no hotter than the other SSD, so it appears this reading is wrong.
I assume now that the SSD I originally thought was dying, wasn't dying and it was just a symptom of whatever this problem is, as that SSD was also fairly new (a few months old). I also assume it has to be hardware related, and not OS related, because It ran slow on linux OS as well.
Would anyone know what this would be?
Bad cable? bad power supply? Motherboard?
Thanks in advance for any advice.
p.s. The screenshot that shows Disk 5 at 93% usage is a USB drive transferring files to another USB drive.
The other screenshot shows file transfer between the SSD's.
