Bought this unit to keep an older MacBook Pro alive. Decided that it would be best to remove the optical drive and install a 249GB OWC Electra 6G SSD with the Data Doubler kit.
I will readily admit that I'm not long on patience, so I ordered overnight shipping. And, the package arrived late this morning. Was going to wait for some solid, uninterrupted time, this afternoon, but I did not. And, that did not hinder the results.
By the way, being thoroughly prepared is important. I use a piece of cardboard with tape attached for configuring scew placement once they are removed. Also, I start at the top of the cardboard and move downward in tiers. Any method is to take pictures during logical points of progress.
This is not a super complicated task unless you do not possess the mechanical aptitude. If you do, couple with the right tools from OWC, you should not experience much, if any, difficulty.
The packaging was superior and the Data Doubler frame is beefy. If fact, you'll need to use extra long screws in two places . . . supplied in the package.
In essence . . . remove the back cover, disconnect the battery, disconnect three ribbon cables, disconnect another plug, jostle carefully the Airport unit and slide out the optical drive. Mount the SSD in the Data Doubler housing and it fits perfectly into place. Reverse engineer reassembly. Voila . . . as they say in France.
I had the operating system and applications on the Macintosh HD and on an external Firewire HD. Had made a copy of the Macintosh HD to the Firewire HD using SuperDuper. Then, I merely copied the external drive to the 240GB OWC drive after formatting. By the way, for SuperDuper to work properly, the drive must be GUID. Finally, started from the new primary drive, 240GB OWC.
No problems with the drive, but there was an indication that I had no Airport hardware installed. This took some troubleshooting, but it cannot be blamed on the OWC products.
