I'm selling this because I bought it to increase the storage capacity of my laptop, but I don't have a use for it. Below is a copy and paste of the specifications and details: USB3.0 connection cable set. Compatible with USB3.0, which is up to 4 times faster than the conventional USB2.0 in terms of execution speed. You can maximize the performance of high-speed HDDs and Blu-ray write drives. Of course, it can also be connected to USB2.0, so you can use it regardless of your computer. The connected HDD will be displayed as a new drive in the "My Computer" of your desktop. You can move (copy) data by dragging and dropping with the mouse, organize (delete) data, and copy entire folders... You can use a larger capacity HDD with the same ease as a USB memory.
