    Do you actually see the two drives? is this something that needs to be managed?(Hope not) When you import pics or downloads itunes I am assuming it does directly to the HD.'

    Thanks!

    It shows up as a single drive. It works like a single drive.

    Expect it's fast.

    10s boot to desktop for me.

    It shows as a single drive, and pretty much every thing goes to the SSD initially, before being moved when the PC has spare resources to move stuff to the HD.

    So lets say you have 128GB SSD and 1TB mechanical drive. If you have 500GB of files, you might have approx 4GB of free space on the SSD with the remaining files on the HD. Any newly downloaded files would then fall into the SSD's 4GB free space. At which point it would then free up some space so it again had 4GB free. What was moved would probably not be the new files, but something older that isn't used as much.

    The article below and the 2 it references explain a lot about how it all works.
