I have a 750GB WD Blue 2.5-inch hard drive I want to use as an external backup drive. I want to put it an enclosure via either an eSATA connection or USB 3.0. (My motherboard doesn't support eSATAp or USB 3.1.)
For this purpose, I can either buy an enclosure that draws its own power from a USB 3.0 cable, or I can buy an enclosure which has a separate power cable. I would rather have the former, but would there be problems associated with drawing power from a USB 3.0 cable, to power a 2.5-inch WD Blue hard drive?

Some 2.5" drives can run via USB power. Some cannot, and require wall power. All SSD drives can run via USB power. All 3.5" drives require wall power.
