Static data raid 5 is a very good option, it has great read performance and
very inexpensive.
Walking on water and developing software from a specification are easy if
both are frozen.

Since RAID5 means that data is striped, of course read performance is OK. As
soon as you talk write performance, however, RAID5 becomes something of a joke
since it was invented back in the 70's to offer a cheap alternative to the fast,
extremely expensive disks offered by IBM back then. So the

Would you stripe 6 for data and other 3 for indexes, or use one 9-drive
volume for both? One side of me says the more spindles the merrier - keep
them together, the other side says - separate data and indexes. The third,

What about redo logs, rbs, temp, system, exe's?
Number of spindles doesn't necessarly mean faster performance. Depends on
the data and the controller. If you set 6 disks with 64 Kb stripe size,
your stripe width is 384 Kb with Raid 0. If your not using a write-back
caching controller, you
