My standard build recommendation on a 2850 is Mirrored drives (RAID 1) on
one channel for OS and TLOGs. Definitely 15KRPM, most likely 73GB. The
other four drive slots can be used for RAID 1+ 0 data on the second channel.
Depending on your actual data space requirements, you can use either 73GB
15KRPM drives or 146GB 10KRPM drives. Remember to order the split backplane
module to take advantage of the extra controller channel.
