Yes! :3
As you are looking at the bottom of the compy, (the drive bays closest to you) the slot at the left is 0, the slot on the right is 1.
MEANING: You put the SSD on the left side, and the HDD on the right side!
Though just a side note, apparently you need to 'hook in' the SSD via your BIOS for the system to know it's your boot drive. And sometimes, the compy might get confused between which drive slot is what unless you specifically set it.
Make sure you get a 2.5 inch drive, also remember you do not need a caddy, just put it in the one that already exists.
Double check to make sure!
