Interesting - 2 out of 2 votes against Promise. I was under the impression that both brands were good and worked well with linux.

Also: It is a little long, but it's only one of many chosen at random.

"work right" means no data loss in every situation except if both disks crash simultaneously (which is a disk error outside the RAID system's control).
