I'd assume that the limit on cached data for Squid is not the number of bytes, but the number of cached objects?
If you were to tune squid to be aggressive about caching large popular objects, then you could certainly fill a terabyte plus cache_dir, but I'm not sure how cost effective it would be overall to build a small number of extremely high capacity caches. My opinion is that unless you're getting these multi-terabyte arrays for free, or your bandwidth is really insanely expensive and high-latency, that the same investment could be better spent building a small number of extremely high *speed* caches; that is fast caches near the end-user and with many spindles, populated with all the RAM you can cram.
