Yesterday I had my internal SSD Boot Drive die... (http://forums.macrumors.com/showthread.php?t=1818064). So, after working the past 24 hours, I now have the Mac back up and running from a standard Internal Hard Drive in Bay #2 with the latest version of Mavericks installed. All of my apps, etc have been restored from my most recent Time Machine backup (thank God for TM when it works!). I had to completely remove the dead Samsung 840 EVO 500GB 2.5" SATA-3 SSD and Apricorn Velocity Solo X2 PCI card in order to get the MacPro to even start-up as I kept getting a "circle with a line through it" on-screen with each reboot attempt until it was extracted (may not have had to remove the PCI card?). So here is my question(s)... I have a new Samsung 840 EVO SSD arriving in the morning. I am initially making the optimistic assumption that the PCI card is OK and just the drive died. (1) What is the best way to transfer ALL the system, apps, data on the temporary boot drive I have now running in Bay #2 to the new SSD Drive (assuming it mounts). Would CCC be an acceptable method to clone everything or do I need to boot from a Mavericks Installer USB thumb drive and do another system install/TM restore routine to the SSD? (2) Another option might be to install Yosemite on the new SSD from a USB thumb drive installer as upgrading will probably be inevitable, but not convinced it is really ready for prime time. I also see there are Trim issues with SSD and Yosemite, etc. right now. But just out of curiosity, if I were to install Yosemite on the SSD boot drive, would I be able to perform a Time Machine Restore of all my apps, etc from a backup made under Mavericks??? Sounds scary!
