ok I caved on the RAID
Written on the original Movable Type site and recovered from the Internet Archive.
I had posted: Deep Green Crystals: My next RAID upgrade but today got shamed into buying the larger disks. What it ends up as is paying $1 per gig for the last half a TB and getting a full 2.0TB more rather than 1.5TB more.
Supermicro (Beige) 5 Bay Hot-Swapable SATA HDD Enclosure, MODEL CSE-M35T-1, New Egg, $113
3Ware 9500s-8 SATA PCI RAID controller, New Egg, $489
5 Hitachi 400GB SATA 8MB buffer 8.5 ms seek time drives, New Egg, $309 each total 1,540
total: $2,142.
