Something seems really off, here's what I'm getting with a software raid5, with 5 old drives. Quantum AS's, ranging from 30 to 60 gig, using a 30 gig partition at the beginning of the disk.

CPU is a single P4/2.53, 256 meg pc2100. Using the onboard promise chips, two drives per controller, and the last drive is on an onboard port. Yes, I know this is not a very good way of doing this, if one drive fails it might take the other on the chain with it. But I'm waiting for Maxtor to actually release(not this vapourware stuff) their 320 gig drives, so I can get ahold of a 3ware 7500-4 and 3 of the 320's, and replace this horrible mess.
