I would expect the 10K drives to be a bit faster, but it depends. The
number you need to compare is the seek time. Raw I/O bandwidth is not
that important when pushing the limits, seek time is far more important
when pushing the limits of Squid disk I/O.

But I don't think you will see a big speed difference between these,
having 4 drives and a lot of RAM. Quite likely CPU will be your first
bottleneck assuming everything is reasonably tuned.

But I should also say that max load estimations of reverse proxies is a
bit hard without knowing the actual workload. Each site is different.
