The results are pretty clear-cut. In most instances, the performance of the solid state drives improved significantly when we switched from Windows Vista to Windows 7. The performance boost was particularly obvious in 4 KB random reads, and 4 KB sequential reads and writes, where the performance of these solid state drives improved by 2-3x!

There were some instances though where upgrading to Windows 7 actually caused some performance degradation. A good case in point would be the performance of the 256 GB Western Digital SiliconEdge Blue in small 4 KB random writes, where it was 3x slower in Windows 7. Fortunately, such exceptions are few and far in between.

For your convenience, we averaged the results and presented them in this concise table on the right. It summarizes the averaged improvement we recorded after switching from Windows Vista to Windows 7 using our collection of solid state drives.

The results clearly show that switching to Windows 7 greatly improves the performance of your solid state drive, for most part. Therefore, if you are using a solid state drive, or intend to use one, we highly recommend that you switch to Windows 7 if you are still using Windows Vista or Windows XP. If you are already using Windows 7, congratulations, you are using the best Windows operating system for your solid state drive.

Please do keep in mind though that we have only been looking at the performance aspect. There are other issues to consider when you are deciding on the best solid state drive for your needs, e.g. storage capacity, power consumption, thermal output, and even warranty. For these and other important details, it's best to read up on the full reviews :

Also, note that these results are solid state drive-specific. They are not indicative of hard disk drive performance.
