Depends on your workload. My workload has a high number of DELETE
statements with a relatively small total set size of recurring SELECT
statements, therefore the buffer cache gets filled quickly and reads
rarely touch disk, though the disks stays busy from the DELETES. In
general, throw as much as you can at the disks unless the budget
prevents your from doing so.
Also, watch out for cheap three disk RAID-5 arrays. There's a crop of
low end servers that have these. Serious trouble.

The postgresql installation manual documents the location of a cluster on disk.
