Thank you for the replies.
Didn't actually know I was using the correct terminology to be honest; just copied what I saw on the website.
As for actual throughput speed - not really worried. I just want 4 of the drives in my Mac Pro (to replace 4 x 1.5TB) to expand my media server.
So long as I can make it into 4 partitions (375GB - Boot, 525GB Music Archive, 100GB Xp Pro Bootcamp, 2TB - Media Archive) then I am all set :-)
