I’m about 2/3 of the way done with writing the Windows 7 tweak guide. I’ve come across an issue that I need some help with. It applies to SSD’s. During my research I found these 2 statements:
“In Windows 7, SuperFetch is automatically enabled for disks that have a low Windows Experience Disk Score and disabled for disks that have a high score.”
Performance Testing Guide for Windows
and
“If the system disk is an SSD, and the SSD performs adequately on random reads and doesn’t have glaring performance issues with random writes or flushes, then Superfetch, boot prefetching, application launch prefetching, ReadyBoost and ReadDrive will all be disabled.” Engineering Windows 7 – Support and Q&A for Solid-State Drives
One problem with the above 2 statements. I have an SSD disk (specifically the Intel X25-M Generation 2). My Windows Experience score for Primary hard disk is 7.7 (out a possible 7.9). This was a clean install to this disk, not a clone or image. According to the above statements Windows 7 should have disabled Superfetch. Windows 7 did not disable the service nor adjust the registry settings. It is visable via Task Manager (SysMain) and is actively using system resources.
I’m interested if anyone has had Windows 7 disable this as they claim.
I would also like to know what qualifies as a high “Windows Experience Disk Score” according to Microsoft. (not really expecting an answer on this)
