Sudden persistent drive performance issue

Featured Replies

One of my drives suddenly just slowed down.  It is operating at about 10% of what it was doing yesterday.  I ran a diskspeed test, and the graph shows the impact.

 

The logs attached will show that I also have a cache drive problem due to a bad cable, but this seems unrelated, as all of my other array drives are affected.

 

Any ideas?

Replace it, or live with with, not much else you can do.

With no error messages anywhere, I wonder if it's the drive, or if the problem is in the controller/cables/driver...

I guess I can remove it and test it in another system.

Very unlikely, but easy to test, just swap cables with another disk.
