I recently had my RAID rebuild and have now noticed a lag in large queries on SQL. I don't know much, so thought I would ask for input. Should I defrag my C and E drives which are on a RAID 5 or is that a bad idea? My RAID rebuilt itself because I had pulled one HD thinking I would put in a new one, for no other reason than to have a fresh new drive. Learned that it takes my RAID about 20 hours to rebuild, anyway, wondering if that somehow made things slower?
