More specifically, for high loads, get fast SCSI or SAS disks, directly
attached, and arrange them in a RAID-10.
Whether or not such a setup is overkill (sometimes it is) depends on
how much load you're really generating. But (as Vick stated) DB servers
are usually bottlenecked on how fast they can access the disks, not RAM
or CPU.
