hello all a newbie question regarding sata hard drives and raid

[alan888]

Hi all

Is it possible to raid 2 hard drives 2 different sizes to another?

Or does raid require 2 of the exact same models?

Yes, but the total disk size will be based on the smallest hard drive.
ie. Two hard disks, 40GB and 80GB.

Raid 0 : Total disk space will be 80GB.
Raid 1 : Total disk space will be 40GB.

It is best to use identical hard drives for raid setups.

Hope this helps!!

I believe some RAID controllers will now allow you to make use of the unused 40GB on the 80GB drive in the above example, albeit as a standalone drive outside of the raid 0/1 array.
