Sata 3.0Gbps - 3 Gigabit per second maximum transfer rate, this corresponds to SATA-2 standard.
5v 700mA DC - This means it needs 5 volts direct current (DC) to run, this is pretty standard for 2.5" drives, and is the voltage of a USB port as well.
700mA is milli-amps. USB 2.0 will supply 500mA per port if it's made to standard, and USB 3.0 supplies 900mA. Many laptops have ports that supply more than that for charging, usually indicated on the port with a little lightning bolt.
Anything USAFRet has suggested will work to connect this drive by USB (I've used Sabrent enclosures and docks, they work well without hurting the pocketbook). If you use a USB 2.0 port, be sure to plug in any secondary USB that's on the cable to be sure you're getting the extra power needed. Sometimes these drives won't need that extra power to run, but others are quite serious about needing that extra juice.
