A 2.5 inch drive self-powered

It is quite elegant and has a green LED on the top that says it is on.

We are in the category of 2.5 "and therefore self-powered by the USB port.

It has a USB Y-cable that allows to use a second port on the PC in case of electric power failure on one port, this is both good and bad, because it mobilizes 2 USB port but can manage low power PC on ports.

I have not had a problem on my desktop PC and so I do not need to connect the 2 USB ports, my ports are adequately supplied.

In these conditions, you should know that I could use a USB cable other than the original, longer "90 cm" without self protection and with only one take, so less bulky and longer , with the same results in transfer rates.

CAUTION This however requires a good quality cable especially great length.

The transfer rate is 34 MB / s read and 20MB / s write for a 50 or 500 MB sequential file is correct for that without without less format.

With 465 GB available, we are dealing with a product of good quality, good performance and a good average. it remains of USB 2.0, but all the PCs are not yet equipped with USB 3.0.

It goes without saying, but so much better to say, this disc is compatible with future USB 3.0 but with course transfer speed of USB 2.0.

The price is right in this category and we have a good quality print.
