I'd have to say that I'm very happy with my Dell 2400, which is configured
as RAID 1+0 (sometimes called RAID 10). As I understand it, this is what
Progress suggests. One of the downsides is scaling: You net 50% of the total
installed HD space. In my case, I have four 9GB SCSI drives, so my RAID 10
array has 18GB of usable storage. My new server isn't all that much faster
than the old one (Dual 550 MHz PIII versus Dual 450 MHz PIII), but I'm
impressed with the speed gain I've seen over the old server, which was
configured as RAID 5.
I have to say, though, that I never had a corrupted DB using RAID 5. That in
spite of a series of 70+ unanticipated reboots due to a flaky motherboard. I
only had to restore a backup once.

Performance was the wrong word I should have said speed Raid 5 is faster to
read and write with the way it spans physical disks. You need at least three
disk drives for raid 5 and two for raid 1 which is also referred to as
mirroring.

Raid level 1 is more reliable but raid level 5 would give you better
performance.
