Hello all, I have a Late 2011 MacBook Pro with a 500GB HDD which is almost completely full. I am thinking about buying an external hard drive to move all of my photos (over 300GB) off the internal drive and then replacing the HDD with an SSD. I had a couple of questions. 1) What interface and/or model of drive would everyone recommend for the external drive? With a Late 2011 MBP, my options are USB 2, Thunderbolt 1, or Firewire 800. Note: I'd like some type of 2-disk external drive so I can set it up in RAID 1 mode. 2) What model of SSD would everyone recommend (probably will get a ~500GB one)? 3) Should I enable TRIM on the SSD? If so, is Cindori Disk Sensei the best way to do it, or is there a free way to do it safely? Thanks for any help!
