There are many benefits to adding a second hard drive to your laptop such as improved speeds, greater storage space, and less heartache when installing new software. Use this guide to install one using our optical bay hard drive enclosure.

  1. Installing MacBook Pro 13" Unibody Mid 2012 Dual Hard Drive, Lower Case: step 1, image 1 of 1
    • Remove the following ten screws:

    • Three 14.4 mm Phillips #00 screws

    • Three 3.5 mm Phillips #00 screws

    • Four 3.5 mm shouldered Phillips #00 screws

    • When replacing the small screws, align them perpendicular to the slight curvature of the case (they don't go straight down).

    • Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.

    • It is useful to pry upward on both short sides of the connector to "walk" it out of its socket. Be careful with the corners of the connectors, they can be easily broken off.

    • Carefully pull the camera cable out of its socket on the logic board.

    • Though not recommended by iFixit staff, some users opt to omit this step completely. For information on this, see the step comments.

    • Pull the cable parallel to the face of the logic board. Pulling it upward may damage the logic board or the cable itself.

Has anyone else noticed their Macbook booting and responding slightly slower with this duel-hard drive setup? I first swapped out my main hard drive for a SSD and the computer felt amazingly quick. I then replaced the optical drive with another SSD for additional storage and backup and ever since then the computer has felt slightly more sluggish in general. I suppose the CPU now has to constantly communicate to the second SSD where it could mostly ignore the optical drive before. Has anyone else noticed this?

Just fixed that issue:

Put the new SSD where the old HD used to be. Put the old HD where the optical drive used to be.

I found that the ports in the motherboard inside the mac have different speeds. The HD port is 6mb/s and the optical drive is 3mb/s.

Are you sure its MB/S that would be horribly slow.

I am seriously considering replacing my old HDD with a SSD instead of using a dual drive. Would you recommend still adding a dual drive with new SSD/ old HDD or just replacing the HDD with an SSD. I like having an optic drive, although not necessary. I am looking from the point of utility and practicality. Cheers!

Zarkex is correct. The transfer speed for SATA 3 is not 6MB/s it is 6GB/s.
