I have used raid aware and non-raid aware disks for both hardware and software raid. You really want the raid edition drives, as they will send a fail up the channel much faster than a non-raid drive. The non-raid drives will retry over and over, and you stand a chance of data loss while they decide what to do. Software raid will just fail the drive and switch to degraded mode.

Ok, and should I mix disks from different vendors? I have read somewhere that this augments the reliability of the array, lowering the probability of 2 disks and more go down simultaneously?
