Can you buy an enclosure for this so it can be used as an external drive?

I tried it in a usb3 dock and didn't get nearly the performance others get hooking directly to sata. About 80Mbps average write speed backing up to capacity with HD video projects. Started out at around 270Mbps but that only lasted the 1st 20 sec or so. I get closer to 100Mbps average throughout with 7200 rpm Seagate laptop drives of same form factor and size. eSata might be a better bet and you won't need an enclosure... no circuitry is exposed as is.

Does it come with software to transfer from a bigger hd to a smaller hd?

Use Macrium Reflect free, download it. Its to copy everything from your old HD to your new SSD. It will help you tranfer from bigger to smaller and vice versa.
