Intel all the way !!
Intel has 250mb Read vs Kingstons 170mb (thats if I have looked at the same Kingtons as you)
I do appreciate this is 4 x 40Gb Kingstons in RAID 0 but the sequential read speed is almost exactly linear in it's increase with RAID;
If 2 x 40Gb Kingstons do 300Mb/s then they'll genuinely destroy the equivalent Intel 80Gb HDD, plus at roughly £150 for the pair, they are much cheaper as well.
wow them scores are very impressive.
is that using onboard raid or a dedicated card.
