The Transcend Storjet units are sold for use with the new USB3 interface systems. They also are marketed as "compatible" with USB2 systems.

HOWEVER, those units do not come with their own power supply unit, and rely completely on the USB port of the host computer for power. They DO work when connected to a USB3 port using the USB3 cable supplied with it. But USB3 ports can supply up to 0.9 amps at 5 VDC, whereas the older USB2 system ports could supply only up to 0.5 amps. Thus the Storjet can NOT work when connected only to a USB2 port - it cannot get enough power.

If your computer has only USB2 ports, that is a problem. I know of two solutions.

1. Earlier USB2 portable hard drives for laptops came with a special type of USB2 cable that had TWO connectors on one end, and you had to plug BOTH of them into separate USB2 ports of the host computer. That way they could get enough power to run. The new USB3 Storjet units do not come with that type of cable. But if you can find one, try using it. That may get it to work if you have two USB2 ports to use.

2. This solution works I know, because I've done it. You need to buy a new USB3 Hub, but it MUST come with its own power supply "brick" able to provide about 1 amps at 5 VDC for EACH port on the Hub. Now, this gets a bit tricky because many of them come with a 12 VDC power brick and it gets changed in the Hub. To sort this out, 1 amp at 5 VDC is 5 Watts PER PORT. So a 12 VDC power brick will need to supply that much power. For example, a 4-port hub would need 20 Watts, or about 1.7 amps at 12 VDC minimum. When you get this, you plug the Transcend Storjet into the Hub using its USB3 cable. Plug the power brick into the Hub - now it CAN provide the power that portable drive needs. Then use a USB2 or a USB3 cable (does not matter) for the connection to a USB2 port on the computer. Now the power for the portable drive is coming from the power brick, and NOT from the USB2 port that can't provide enough.

With either of these arrangements you get the drive to work BUT its data transfer speed will be the slower rate for a USB2 system. That is because it is limited by the speed of the slowest part, the USB2 port.
