Hi all. My 2009 iMac is dying. Actually I have Lightroom and all my photos at it's internal 2TB HDD. So I'm thinking to buy the "new" 27 inches iMac with 512GB SSD ( well, maybe 1TB ) and move photo library to 2TB external drive. My question is - which drive to get - 3,5" with it's power supply or USB powered 2,5 inches ? As I can see there are some 2,5" really fast.
Thanks in advance
Best,
Igor.
