These are some performance stats from network admin who have been
willing to donate the info publicly:

As for the OCZ question, Squid has been known to burn through SSDs a lot
faster than manufacturer claims of their lifetime. Squid traffic is
mostly-write with >50Mbps write peak rates where SSD are manufactured
for mostly-read I/O patterns. I've recently been told of one ISP
reaching around 100Mbps writes on average with no trouble at all.

The OCZ is rated well above that, so is unlikely to be a visible
bottleneck. You are more likely to be throttled by the speed Squid can
parse new requests. Which is CPU bound.
