Looks like a fibre chanel hard drive array judging by the connectors in the back. Love the way they list the original 31K price. Also they can easily read the size of the drives to give you a toatal drive size. But I imagine each drive is only 9 or 18 gig so they won't list the size.. Instead they list how much Nasa pid for it 12 years ago.
in other words it's junk. Get a big scsi drive and you'll do fine on an Amiga.
