So here is a question I have a lot of content that needs caching Is there a big performance difference in say a machine with 4x250 sata 7200rom drives vs 4x150gb 10krpm sata drives? Each machine has 8Gb ram these squids are acting as content cache from a san. Or even would there be a huge difference with large 7200rpm sata drives? Currently I have squids on a 73gb 10k sas drives and they are handling ~70MB file downloads with no problem, though the average file size is around 350k according to the squid info. Cheers, Zak
