Hi all, I have read through this thread and would really appreciate it if those of you in the know could have a look through the process below and tell me if it is likely to work and if have missed anything. 1. Remove media files from Toshiba 750gb HDD so that the drive has less than 250Gb on it (I am going to re-sort these and switch to iPhoto to manage them and keep the originals on an external drive) 2. Run Time Machine Backup 3. Open mac up & remove superdrive 4. Remove HDD & install into optibay/superdrive caddy 5. Install caddy with HDD into optibay/superdrive 6. Install Samsung 840 250Gb SSD into main bay 7. Put MBP back together 8. Boot from old HDD (using option key when powering on) 9. Update & format SSD 10. Use carbon copy cloner to clone HDD to SSD 11. Check SSD by booting from it 12. Re-format old HDD 13. Re-organise files across both drives (user/home profiles etc as per http://mattgemmell.com/2011/06/21/using-os-x-with-an-ssd-plus-hdd-setup/) 14. Run time machine backup 15. Import media files into iPhoto library on HDD 16. Enjoy a much faster MBP with a little more noise and more care because of the lack of SMS to protect HDD. Is that likely to work? I am also wondering if it is worth cloning my HDD to an external drive or running another time machine backup between 11 &12 as well just in case. Thanks in advance for any input.
