Thanks for reply,
Yeah i have noticed an increase in loading times of large files and games,which i was expecting but it was just these benchmarking software that had me wondering.
I have had IBM deskstars 7200 for last 4 years but are terribly unreliable due to faults in newer drives, and the last 3 ibms iv had back this up LOL.
Quite impressed though with the performance of the baracudas.
