The Universal Serial Bus (USB) is one of the most common computer interfaces. It is a universal connector that works the same way for any device. Thanks to its Plug and Play functionality, it allows for automatic installation and is compatible with all operating systems. The data transfer speed for USB 2.0 is 480 Mbit/s, while USB 3.0 offers a speed of 4800 Mbit/s.

The rotational speed of the disk inside a hard drive greatly influences its read and write speeds. The higher this number, the faster the speed.

2.5" external hard drives receive sufficient power through the included USB cable. It is not necessary to connect them separately to a power outlet using a wall adapter. However, due to their higher power requirements, 3.5" external hard drives cannot rely solely on the power provided by the USB port. The box includes this adapter for them.
