Portable is a strong word. It's not so much a portable drive as it is a desktop external HDD that utilizes USB for data transfer. Technically portable, but not really made to toss in your pocket. It wouldn't be an external drive if I hadn't run out of headers before I wanted it. And I already had stuff on my other drives so I couldn't just swap one out. I mean, I could, but I dedicate them to things - system drive, games, raw video captures to edit, exported videos that have been edited / miscellaneous, and then this external drive for phone backups and archived media.
