is it okay to defrag a raid 5
Q: Benefits to defragment a Raid 0 SAS (2 disk) in Windows 7 Just wondering if there are any. Do not defragment RAID 0 or RAID 5 arrays. There is no point since the RAID controller determines where the bytes are written to on the two (or more) physical drives.Any benefit you receive will be extremelty short-lived as a few writes later you will be extremely fragmented again.See, the problem is Windows sees RAID 0 as a single drive and defrags it that way. The RAID controller does not. If the RAID controller wrote data only to one drive then defragging would help.ny benefit you receive will be extremelty short-lived as a few writes later you will be extremely fragmented again.
