Correct me if I'm wrong: Your using an external drive for your OS?
Yes, the Cable that it came with is a SATA TO USB Data Transfer Cable. This is also the type of SSD that Crucial Recommended for my Mid Year 2010 Mac Mini through their SSD Drive Compatibility Assistant. I simply bought the $123.99 128 GB SSD that they Recommended! It is indeed an External Drive due to the fact that the Regular HDD Does NOT come out of there or else you VOID your Extended Apple Care Warranty according to the Mid Year 2010 Mac Mini's Owner's Manual! Just FYI!
