[QUOTE="Raz0rEdge, post: 1797185, member: 110816"] There are multiple factors at play here. First you want to figure out the speed of the SSD itself. The regular ones usually support up to 500 MB/s read and write speed. Some of the more fancier (and expensive) ones might go beyond that. Next, you need to figure out the SSD is connecting to the external enclosure. If it is a SATA connection, then you'll want SATA 3 which can go up to a theoretical 600 MB/s. The other connection type is PCI-e (PCI Express) that can go up to 2.2 GB/s (or nearly 4x faster than the SATA 3 speed). The last part of the chain is connecting the enclosure to your Mac and that can be over USB 3 or TB 2. USB 3 will max out around 650 MB/s and TB 2 will max out at around 2.5 GB/s. So, bottom line. If you go with a SSD that read/writes at 500 MB/s and is connected using SATA 3, then you'll be fine with the USB 3 connection. If you find a faster SSD that can use PCI-e, then you'll want to go TB2 to ensure that you are talking to the device at the fastest supported speed. [/QUOTE]
