That's about on par for a standard 7200 rpm sata-2 drive in raid-0, what were you expecting, 300+ from two drives? Each one alone would only score 50 MB/sec - 60 MB/sec.
Edit: Asus website says your motherboard has ICH10 on it, although it might not be raid.. i'm not seeing anything about configuring raid in your motherboard's manual, so maybe not... sorry i posted a reply eariler thinking you had the onboard-raid chip.
just my 2 cents anyway.
OK thanks, its on win 7 btw
I'm confused as well. If I understand the above statement correctly, it suggests I get the same performance with 1 new gen 1TB drive as with a pair of 500GB drives in raid-0???
If my above statement is correct, would I be better off with a single new gen 1TB drive vs a pair of 500GB in raid-0??
Hmm... looks like all my drives are the "F1" models. So you may want to disregard my results if the F3 is supposedly a lot faster. Sorry for the confusion
I may be talking from my rear here, but I notice that the OP's graph is very flat, where generally a HDTune graph will curve downwards as you go across the surface of the disk - as is seen on some of the other graphs posted here.
I believe this downward curve is related to the time taken for the heads to move out across the surface, hence lower average throughput the further the heads have to move. But the OP's curve is flat. . . so this mechanical issue isn't what's limiting the throughput.
