Squid does not care about partitions. Two partitions on one drive spindle
with a cache_dir each will have as may IO clashes as two cache_dir on one
partition on the same drive spindle.

Per Spindle.

Partitions only matter if your drive is advanced enough to have multiple
independent read/write heads and your partitioning is fine grained enough
to match exactly to a particular platter.

The disk rule-of-thumb generalization is one physical disk one cache_dir.
The exception being COSS which can be paired with another cache_dir type on
one drive.
