HD transfer Sustained measurment question

[Jerukoth]

Quick question... I have three drives in my system (Four Physical)

2X 74 Gig WD Sata Raptors running in Raid 0

one SATA 160Gig Seagate 7200.9 Barracuda
one SATA 300Gig Seagate 7200.8 Baracudda

HD Tune reports the sustained speed for the Raptor array at 101 +- with bursts as high as 160

The 160gig reports at 70+- with bursts to 100+

the 300gig is 55+ with bursts to 100+

Is this normal? What ranges should I expect from a raid 0 array?

Thanks

That's about what I'd expect.
