I think the next time I need storage, this is exactly the route I'm going to go. No drivers to hassle with (on the OS of your choice), etc. They quoted me $4,212 USD for a 435 rackmount with 480GB (six 80GB drives). The prices get remarkably better the bigger you go: 1.08TB for $4,632 (until Friday, according to the quote). I also keep meaning to get my 3ware IDE RAID card running under Plan 9, but I lack motivation. (I have a 2-port I might be willing to lend out if someone feels energetic.) I suspect most of us are just using fs, though: http://plan9.bell-labs.com/magic/man2html/3/fs -Jack
