Yes, to squid anything over 20GB is 'large', though 'huge' is in the TB
ranges.

The default garbage collection boundaries are very heavy-handed and may
cause periodic slowness while tens or hundreds of MB in small KB files
are erased.

Squid can handle up to 63 cache_dir. Each one ideally on exactly one
unique HDD / 'spindle'.
IIRC Henrik last spoke of 3 HDD being optimum for access vs data
retention. With minimal gains going to more. I'm not sure if thats changed.
