TweakTown posted a SSD performance comparison between Windows 7 BETA and Windows Vista SP1

The topic of SSDs itself is rather interesting, but when you team up the increasingly popular flash memory technology with Microsoft's next operating system, Windows 7, things move up to the next notch on the excitement level - for us around here, anyway - but probably you too, if you are reading this.

We have gotten hold of the Windows 7 BETA and today we are going to compare the performance of single SSD as well as RAID 0 SSD in W7 and Vista SP1. Keep in mind this is just a first look; Microsoft may still and probably will provide further performance optimizations for SSDs under the final shipping version of W7 and this is merely a look at the performance difference so far. We didn't even install any new drivers on our W7 beta install - just ran with what was built-in, so it is a good raw look at things currently as they stand.
