People have suggested on this list that there is no advantage to
partitioning a drive used for cache storage, so you can probably save
yourself some bother by juts using one large partition.

This apparently depends on your filesystem - it's been suggested that for
Linux's ext2fs you are better off using 254 files per directory than the
default 256. Beyond that, you're unlikely to get any improvement. From
discussions on this list it doesn't seem to be an area really worth
putting much effort into - the gains appear to be minimal at best.
