MS is promising a faster experience with Windows 7 and the way it handles solid state drives. We put that to the test with the public BETA release.

A note on Access Time and CPU Usage

 

Windows 7 BETA vs. Windows Vista SP1 SSD Performance Compared

 

The above result from HD Tune Pro is of the SSDs in RAID 0 under Windows 7.

 

We wanted to note that every single configuration (read and write) saw an access time of 0.2ms and that is a great result.

 

When it came to CPU usage, however, there seems to be a discrepency with the info reported under Windows 7. In every test we saw a CPU usage of -1%. This is clearly an error of some kind, most probably due to the software not yet fully supporting the Windows 7 operating system. Under Windows Vista, CPU usage ranged from 2 - 4%.

 

That is more good news on the W7 + SSD front!
