Hi everyone, I am contemplating installing a small SSD (~240gb) drive on my 27" imac, but have some reservations I was hoping you could tackle for me. I will be engaging the services of a hardware vendor to get it done for me, so that is not an issue. What I am concerned about are the files on my existing HDD. How might I go about transferring the critical system files that I want benefiting from flash onto the SSD after it has been installed? I don't think I can just drag and drop? I understand what some people suggest is to first back up my imac, then do a fresh re-install of lion, finally restore. However, I downloaded my copy of lion directly off the app store, so how would I get another copy? Is it possible to just get it from the app store again? Also, I have a lot of files on my HDD, more than the SSD I will be installing. Is it possible for me to choose what gets restored to where? Lastly, for backing up, can I just use any external HDD? I do not have time capsule, nor do I really have a habit of backing up my computer as my work-related stuff is either on dropbox or thumbdrive, so do excuse my ignorance in this aspect. Plus any other tips and advice before I get it done? Thank you all for your advice.
