Good advice, but not always so. I've had very good luck migrating between/among even different (chipset) brand of controllers *so long as* the array was simple RAID1. All bets are off for RAID 5 (3, 4, 6 ..et al), of course. Also with RAID1 (only), nary a problem mounting a surviving HDD to a non-RAID controller. SCSI, of course. (P|S)ATA too-often-pseudo RAID is another matter - and given the general fade-out of SCSI, an important one. > > That's the main disadvantage of hardware raid over software raid - if the > controller dies, you're dead in the water unless you have a spare that's > exactly the same time.

This presumes same OS and reve level (taking ATACONTROL and GMIRROR as examples).
