Well, that looks like a 7.9 to me

nice score, i'm still waiting for the prices to go down. I want a big ssd of around 250-300gbs but I don't want to pay the price they have right now. So i'm playing the waiting game to see the prices drop more

If you have the Intel chipset then I understand you may get better performance using Intel drivers in place of the MS drivers (msahci). Others may care to comment.
It's an AMD system and I got better performance with Window's drivers than with AMD's which is strange because my C300 at home is much better with AMD AHCI.

If that is for a laptop, a bigger SSD may make sense. But for a desktop, 60GB or 80GB are really enough.

Ok, here are my new numbers using the WINSAT DISK command:

What SSD are you testing? The last four lines are latency figures for read and write; you are looking at around 1/2msec latency for both (on average), which seems a bit high for a single SSD. RAIDed SSD's will experience a tad more latency just for the overhead, so perhaps you've got two SATAII SSD's raided together? Also your maximum latency is WAY out for an SSD (even a RAID set), which makes me wonder if your drive might be due for a zero'ing.

Certainly they aren't bad numbers, but this tool provides a level of detail that allows you to do a different 'level' of analysis.

Sorry, I have 2x120 GB SSD (Corsair-Force GT 3) in a RAID 0....They are only about 1 month old...if that..

Ah, cool. Yeah, the RAID answers the extra latency then, so overall those are very good numbers! I might have expected your "long IO's" to score a better (a lower number of "units" is better; units in this case is milliseconds per IO request) but it may be something specific to the Intel controller that I'm just unaware of.

I know most people really place no value in WEI (and rightfully so...) but the WINSAT tool provides a great level of detail for digging into performance data on your machine and its various subsystems. It's too bad Microsoft didn't evangelize it correctly
