Windows 7 and SSDs

Solid State Drives (SSD) are great, but going into that upgrade blind can leave you with less than impressive benchmarks. There are a few things you need to know before adding a SSD to your Windows 7 PC. Ed Bott has an article worth reading called Windows 7 and SSDs: Setup secrets and tune-up tweaks. One of the most important things to know abotu is what TRIM is and how to make sure you're using it. As Ed shows you, it can mean the difference between 10.77 MB/s random reads and 130.25 MB/s, a difference worth knowing about.

    is Win7 smart enough to disable prefetch and background defrag for us when SSD is installed?

    I ordered a pci express ssd card. I'll let you guys know if it was worth it.
  • How to move user profile to another disk? I want use SSD only for system, and HDD for profile and documents.

  • Yes. Defrag and prefetche is disabled. If you want to have you data on the HDD then I recommend that you setup your libraries to be located on the HDD and remove the locations that are on the SSD.
  • @wegl: I did this during my first foray into the world of SSD technology.  I was using win7 and a 30GB SSD.  When I did it, I booted into safe mode upon new install, created a temp admin user with a different profile location.  using that logon, I used xcopy to move the user files to the new drive.  I then created a 'hard link' from c:\users to my HDD drive path.  There are some good instructions online to do this.  It was a real pain in the butt when that spindle based drive failed.  Something to consider.

  • @deadonthefloor: I try to create hardlink, mklink /D C:\Users\MyName D:\Users\MyName, but MS Live Mesh and  RIM BB Desktop dont work. Live Mesh sync my Favorite and it's don't like link.

    @wegl: I went through this myself recently, I've got a post on my list on how to set this up. Stay tuned, I'll try to move that up in my stack rank.

    FWIW: I've got a SSD as my primary in my Envy 17, it boots from cold to Windows in less than 28 seconds. I use the USB 3.0 port with external 32GB SSD's for HD video editing that runs like butter.

    This is the link that I had in my notes for changing user directories to a new drive.
