I'm finally picking up an SSD for my 13" 2010 MBP to breathe some life into my old, faithful computer. I'm looking for a reliable drive that won't slow down/degrade over time and I'm hoping to get at least 2 solid years out of the drive. I'm thinking that the best drive for me is either: Crucial M4 (120gb) or Crucial M500 (120gb) I'm not sure which one to pick up. I doubt I will see any difference in read speeds between the 2 drives seeing as I'm limited to SATA2 (I'm coming from 5400rpm.. even SATA2 will be a huge jump). Can anyone help me out here? Finally, I'm also thinking of picking up a drive enclosure like this one: http://http://www.amazon.co.uk/BIPRA-External-Enclosure-Laptop-Powered/dp/B001EEQQ8Q/ref=sr_1_10?ie=UTF8&qid=1380134929&sr=8-10&keywords=2.5+drive+enclosure Am I correct in thinking with the drive enclosure I can: 1) Connect it temporarily to my SSD and transfer my files from my old hard drive using something like carbon copy cloner. 2) Connect it permanently to my old 5400rpm drive and use that as a backup time machine drive.
