Yesterday I published a blog post entitled “Why you should move your VDI to Windows 8” comparing different versions of Windows during IDLE and Login process. One of my readers (John Hardman) suggested that I also should measure disk IO commands issued from multiple Windows OS during boot time.

What I found in the additional test is another pretty compelling reason to move VDI environments from Windows 7 to Windows 8. In this test Windows 8 excelled when compared to Windows 7. During the boot process there were 54% less write IOs and 39% less read IOs at peak time in favor of Windows 8.

The average IO consumption, for both read and write, were approximately 50% lower when compared to Windows 7.

Windows 2K8 also demonstrated interesting results with lower peak and average IO for reads than any other Windows version. For write IOs it didn’t do so well, but still better than Windows 7.
