I have often wondered about this question, and maybe someone here may know the answer. I am running 2 serial ata hard drives in raid 0 and was wondering weather or not windows defragmentor takes into account the fact that the harddrive is infact 2 drives in raid 0 and defragments it properly.
On the other hand I don't think it does? Can anyone clarify this?
Raid 0 creates one logical disk. To the OS, it's no different than a single hard drive. RAID 0 is striping RAID. This means that each every other 16kb of data in the logical drive is assigned by hardware to a different disk. The OS has no clue, so defragging will work normally. When the data is re-organized and shifted to the front of the "disk", it is still split between the two drives, giving you your performance boost.

Question: Raid0 / Defragmenting. Good or bad?
