Need More Space (or Speed) on Your SSD? – Part 3, Final (Feature)

As promised this will be the final of the three-part series we did for Need More Space (or Speed) on Your SSD?, also if you happened to miss our previous articles – check out Part 1 and Part 2 (respective links). A brief explanation of our following tweak, the Search feature in Windows indexes certain files and folders on your drive and the index itself is found in C:\ProgramData\Microsoft\Search with the space consumed being about 10% of the total contents being indexed. The space consumption may not be worth it for some due to the already fast nature of SSDs since the search indexes are cached to RAM from the drive.

Disabling Superfetch and Search services

  • Type services.msc in the Start menu Search textfield
  • Scroll down to Superfetch then right-click and select Properties
  • For the Startup type drop-down menu, select Disabled then hit OK
  • Scroll down to Windows Search then right-click and select Properties
  • Click the Stop button, change the Startup type drop-down menu to Disabled and press OK

Disabling Prefetcher and Superfetch from the Registry

Reason behind it? Well, Superfetch is setup to cache files that are accessed frequently since SSDs already have fairly low seek times, so the particular function can be disabled. However if you did a fresh install of Windows 7 on a SSD to start with, Superfetch should already be disabled (may not be if you imaged your OS from an existing HDD). On the other hand, Prefetch loads parts of program files and by disabling this you can free up more of your system memory.

  • Type regedit in the Start menu Search textfield
  • Choose the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\Memory Management\PrefetchParameters path
  • Right-click on EnablePrefetcher and EnableSuperfetch
  • Choose Modify on each then change the value from either 1 or 3 to 0
  • Restart your system

We hope you all enjoyed our three-part series on SSD optimization and appreciated the extra space or performance boost. Until next time.
