If you want to transfer a larger amount of data, the Seagate Backup Plus Portable 5TB Black external hard drive is just what the doctor ordered, providing a whopping 5000 GB of portable space. This is enough to back up a large number of files and video content in top-notch quality. 2.5" drives are designed mainly for all minimalists and users who like to pack up a lot in as little space as possible. One great thing about HDDs is their lower price and large storage capacity. On the flipside, their mechanical parts don't take shocks and bumps well. The Seagate drive uses USB 3,2 Gen 1 (USB 3,0) and Micro USB-B interface.
