expecting it to have raid 5 across 16 drives with 1 spare
You might want to evaluate a multilayer RAID setup with that many
drives. I've found 0+1 (striped mirrors) and 0+5 to perform as well as
plain RAID 5 but suffer a non-noticable degredation when a drive
fails. In an odd note, my 0+1 array on an LSI card actually got faster
everytime I pulled out a drive.
16 Raid Drives Western Digital 200GB WD2000JS SATA II 7200RPM 8MB - OEM
Get the Raid Edition drives from WD. 1.2million hours MTBF at either
80% or 100% duty cycle. Their consumer-grade drives are only spec'd
for 20% duty cycle, and are also less tolerant to temperature (thermal
gradient and max operating temp).
