Long story short, I am using the steamtool application, which was originally developed for the following reasons:

  • Steam by default would save all your games to C:\
  • SSDs are becoming the new primary drive for gamers
  • This app will use an NTFS junction to create nothing but links from the SSD, to a larger, slower magnetic secondary drive, thereby saving space, but Steam will think the files are still located in the default directory on C:\

Sounds all fine and everything, and today Steam will now let you choose a secondary drive manually, but I want to use the tool for a "backwards" purpose:

  • I want to create an NTFS junction from my slower magnetic drive to my faster SSD to load my games faster
  • I would only keep 1 or 2 games on the SSD at a time, and I'm not worried about the NAND write cycles.

With only a basic understanding of inodes and those types of structures, my question is whether I will actually get any performance increase by creating an NTFS Junction from my magnetic drive to my SSD, or since all accesses go to the magnetic drive first, I won't get any increase.

  • As a side-note, I'm not asking if the tool is capable, just whether it's worth it. Jan 19, 2013 at 17:06

Steam no longer requires you to install games on C: (or whichever is your steam installation path), you can pick any drive and create another library there. You can have multiple libraries, for different games.

Even though it does not answer your question, it probably addresses your original issue.

    This doesn't work for all games though. For example the older source games don't as they share resources. Jan 20, 2013 at 2:14

    @DavidC.Bishop: You are right, I did not realise that. I was prompted to select a library for Warhammer before downloading, but there is no prompt for Half Life 2. Interesting... Jan 20, 2013 at 2:17
