Hi All, so i recently bought a refurb Late 2012 imac which was the higher base model MD-096 B/A. It came with the standard 1TB hard drive. Now that i have a bit more funds, i wanted to buy an SSD and connect it up and use as the primary drive. My question is, which is better... SSD via USB 3 or SSD via thunderbolt? Which will give me better performance? Also, i am in the UK, so if anyone has any particular drive/setup i should purchase, could you make it uk specific?
