Hi, My DVD drive in my late 2008 macbook pro has given up the ghost (in part helped along by my trying to get it working again when it was refusing to accept discs - oops!). Rather than replace the optical drive, which I probably use about once every three years, I thought I would take the opportunity to add a second hard drive. I currently have a 640gb HDD (aftermarket) which I would use as the second drive, and then get hold of a SSD to use as the Operating System drive. I've earmarked the following products (on ebay, but available elsewhere also, it would seem): SDD drive: http://www.ebay.co.uk/itm/121026940563 Caddy: http://www.ebay.co.uk/itm/130757823914 Could anyone advise whether these are suitable products, and whether there are any potential pitfalls? I am assuming that it would make sense to put the new SSD in the macbook's primary HDD location, as this will be the 'main' drive, and then put my current hard drive in the caddy. Any help would be much appreciated.
