I have one ofe those thingies running our local samba server, raid 5 w/ 3+1
80 Gig 7200 IBM HDDs. Works flawlessly and fast. hdparm shows the following

 Timing buffer-cache reads:   128 MB in  0.87 seconds =147.13 MB/sec
 Timing buffered disk reads:  64 MB in  1.31 seconds = 48.85 MB/sec

This is on a dual PIII/500 w/ 256 MB.

Not the cheapest one, but it's actually worth it.
