HDD access times seem really high

[grimey]

Seagate 7200.11 750GB RAID 0, 128k strip size
HDD's flashed to latest firmware
MSI p55-gd65 w/ intel onboard raid controller
intel matrix control manager is installed with NCQ and write back caching enabled

my transfer speeds seem fine and normal, albeit a little better than I expected, but my access times seem way off. I wonder if this is the reason why my games are feeling real glitchy and stuttering.

btw my transfer rates were just a bit higher in windows 7 than this run in xp but my access times were about the same.


heres a screenshot of my access times using the latest hdtune

and here is the transfer rates which look pretty normal.

i ordered 2 western digital caviar blacks 500gb which im gonna install in a few days. should i be expecting much better performance from the caviar blacks over my current seagates?

and what could be causing these really slow access times, and what effect could they have on my computers performance.

thanks

Way off? Seems pretty reasonable to me, especially with that fakeraid in there.

49ms for 1MB
24ms random

that seems normal?

Have you ever used this test before? These are fairly typical results. Maybe a little worse than I'd expect on the 1MB test, but within reason. Considering the fakeraid is there, not bad at all.

For example here's a random 320GB drive in the machine I'm sitting at:
