I think they're both
A5200's if they're the 22 disk ones. The 14 disk units (like I have) were
initially just badged as A5000, and later changed to A5100 when the 22 disk
version came out as the A5200. They use the same interface boards, power
supplies and I think the same internal planar boards. The plastic guides for
the disks and of course the backplanes are different. I'm running three A5100
(14 drive) arrays in my home server, all loaded with 147 gig FC drives. A lot
of Fujitsus, some Seagates. Basically whatever I could find surplus and on
eBay. I'd LOVE to find a 22 disk A5200... I'm out of space in that rack :D

Hmm. I've had very little problem plugging
random disks into these arrays. I slowly accumulated the 147's to replace the
9's that were in the arrays when I got them. Every (functional) drive I have
found has worked just fine, although I've had one or two bad ones. In one
case, I had a few Fujitsus that were shipped improperly, and some small
inductors were crushed on the drive circuit boards. A couple of these faulted
immediately like that, others ran for a few months before finally failing.
Every other (non-damaged) drive just worked. The last one with a cracked
inductor like that died a month ago, dropping the loop when it failed.
a drive with an odd format (520byte/sector) will spin up, but just won't be
recognized by the OS. A drive has to be seriously bad to fault out directly in
the array and take out the loop.
I'm leaning towards just a bad disk, myself.
I've never seen a 300 gig FC drive before though. Is it a SATA drive with a FC
bridge or something? I wonder if the drive is even dual ported - that's kind
of a feature unique to true FC drives.
