I had been thinking a long time to let me install an SSD in the Macbook or to upgrade with a new purchase on a. The Apple Store prices have been far too expensive and also individual SSD's cost as a 512GB version more than 1,000 euros. Now that they have become cheaper, I slammed directly and was wondering how to upgrade is the easiest to perform. A small SSD in hardwrk adapter instead of the optical drive never came into question for me anyway. The repair gurus of iFixit dot com recommended a program called SuperDuper! and an adapter that no longer exists. Since this adapter came into play. Due to good reviews I slammed and was not disappointed. Provided new single plate by the supplied power cable to power and connect with also supplied SATA cable and adapter via USB to laptop and you will be recognized. Switch to the Disk Utility once on "Mac OS Extended Journaled" and via SuperDuper! Create a complete copy. I had previously installed a 750GB Toshiba HD with 5400rpm and saved 470 GB were copied in skimpy 7 hours the SSD boot was now set up. Von wegen unsuitable for larger copies - nothing was warm, and also sits all bombproof. You could also run overnight. Then unscrew and replace board (PH # 0 and Torx T6 need) and within 15 minutes you have significantly enhanced performance under the hood. No other hardware upgrade will bring a similarly visible performance increase with it.
The cable you need probably only once, but since everything went smoothly, I would highly recommend it.
Edit: That with the "only once need" can I revise already. I have installed the old hard drive out of the Macbook in my Playstation 3 and was able to use the cable again for good.
