Here's three datapoints from the benchmark using my RAID 1 Seagate drives.
Block Size Write Read

Thank you for posting, Barry! I didn't mean to make this harder than it needs to be. Hopefully this will help. If you can eyeball the approximate average Write and Read thruputs for 64KB - 8192KB transfers, then post here. So, take the red Write lines, and look at the x axis in MB/Sec, and estimate the average, since they're all likely similar anyway. Then again for the green Read lines, here's the screenshot again for reference:

Then perhaps edit something like this format below as a template, that'd be great, saving the trouble of screenshots. Here's a synthetic example, based on guess-timates from your posted data:
==========
OS: Vista x64
Model: W700 Quad Core 2.53GHz
Settings: Device Manager, Drives, Drive Properties, Policies tab
Optimize for performance (radio box checked)
"Enable write caching on the disk" checkbox on
"Enable advanced performance" checkbox off
Antivirus disabled
Tool: ATTO Disk Benchmark v2.3 32 bit
Approximate average for 64KB to 8192KB transfers:
C: 60MB/Sec Write, 60MB/Sec Read
W700 with RAID1 [BRAND MODEL SIZE RPM of the drives]
D: 80MB/Sec Write, 80MB/Sec Read
W700 with UltraBay SSD [BRAND MODEL SIZE RPM of the drive]
==========
I realize this scheme may be flawed, and perhaps somebody has a truly free (not trialware) tool to suggest that is simpler to post results from, I'm all "ears." Best would be text output that we could cut-and-paste here to minimize the effort required.
