I have 4 identical Seagate 7200.11 HDDs and Asus P5Q Motherboard on Intel P45 chipset. When i combine 2 HDDs in Raid-0, i'm getting 400 MB/s max and 200 MB/s avg speed, and that makes sense, because it's like double of 1 HDD's speed.
I don't believe you no way can only two Seagate 7200.11 HDDs give you 400MB/s max four of them yes but not two.
Even one on its own wouldn't max upto 150MB/s
Yea i guess i mixed up some measurments (not sleeping at night is bad, mmkay? ). Now i see.
