It’s very good. Now play around with PCWizard & compare.
You are using a Raid configuration and it really shows that Raid 0 is better than any Single HD no matter what RPM it is.
Yes that’s right, however compare the top two graphs. Same drive different s/w. I wonder how your drive compares using PCWizard. The reason for this is that HD tach may misreport Raid. Looking at the PCWizard results are not as great.
