Hi Guys

i have what i think is an issue with my drive's i have x2 Agility 3 60gb drives

i have the asus P7P55D-E mobo, originally i wanted to use these two drives in the 6gb/s Ports to raid them, but apparently i cant as i tried every bios setting there but the raid tool would not show up when i was using "Ctrl + i" at post, as soon as i put them into the lesser 3gb/s sata2 ports Bingo....it worked

thats my first question....does raid 0 work on SATA 6Gb/s ports??


settling for second best i thought id bash on and setup a raid on the SATA 3GB/s ports and set the stripe size to 128k....installed windows 7 quite fast i must say, however upon bechmarking it im not sure im getting the performance i should be for x2 drives rated around 500Mb read/write in a raid 0 setup

look at this link from OCUK thes guys are having the same performance if not better from x2 vertex 2 which is half the read/write speed??

ok so ive reacherced a little more, and found it to be not as bad as i thought although i think these figures are still low as in theory i can have 600MB/s combined, i know its unrealistic to get the full 600 but id ecpect at least 500+

Sata 2 = 300MB/s transfer?
Sata 3 = 600MB/s transfer?

if so i still think these figures are low...
 
thanks buddy, you'd still think those figures are low for the setup ?

am i concentrating on CDM to much? as at ATTO seems not to bad

anyone have any ideas for why im having trouble with setting RAID 0 on 6GB/s ports?
 
Top man, i was thinking of the same conclusion as yourself, but wanted a real opinion to settle the score...

raid controllers are something ive never really dabbled in, i will of course have a look and try to pick the best option but have you any recommedations?

Thanks again buddy
