SDD is better for reading data and a HDD is better for writing data.
SSD are limited in size so I can only keep a select set of data on it...

  • Should I install Windows on the SSD or on the HDD?

  • Should I create junction points (soft/hard links) to move folders between the SSD and HDD?

    Eg. Temporary folders would better fit on the HDD,
    Program Files should be on the HDD but Games I play the most would fit better on the HDD.

    SSD:\Windows\Temp would be REPARSED to HDD:\Temporary Files\Windows
    SSD:\Program Files would be REPARSED to HDD:\Programs,
    HDD:\Programs\A Good Game to SSD:\Program Files\A Good Game

    Or will the REPARSES from the HDD to the SSD cause too much overhead?

  • Are there any other tips regarding which data should be put on which drive?

It's not quite as straightforward as "SDD is better for reading data and a HDD is better for writing data". SSDs are excellent at random writes, and most SSDs are good at sequential writes. But the downside is that an SSD has a limited number of writes in its lifetime. – sblair Aug 22 '10 at 21:47
Yes, indeed. It's because of the downside I don't want to write to it unless needed... – Tom Wijsman Aug 23 '10 at 11:05

Windows, and games should be on your SSD. Temp files on the HDD. There are many other tips.. I would suggest doing some research
