Defrag a RAID-5?
« on: March 20, 2009, 04:38:06 PM »
Any issues or problems with running defrag on a RAID-5 array?  Or do you even need to?  I've got three 500 Gb drives in a RAID-5 array (using the onboard RAID controller on my Gigabyte motherboard) which Vista Ultimate 64-bit sees as a 1Tb drive.

Run it.   Even though you have "three layers": the physical drives, the array controller, and the logical volume.   They are still read as one volume and should be treated as such.

You will not harm anything, go ahead and run it.

Any particular reason you're running RAID5?

Feel free to answer 'mind your own business'.
