This unit is the Seagate Basic Portable 5TB external hard drive, an entry-level 2.5-inch USB drive designed for straightforward backup and extra storage without any bundled software or extra features to worry about — plug it in and it just works. Inside is a 5400rpm mechanism spinning at 5TB of capacity, enough for a large photo/video library, a full system backup, or simply offloading files from a laptop that's running low on internal space. It connects over USB 3.0, which is backward compatible with older USB 2.0 ports so it will still work (at reduced speed) on an older PC. The compact black housing needs no external power adapter — it draws power directly from the USB port — making it genuinely portable for carrying between home, office and anywhere else a quick backup is needed. Seagate covers the Basic Portable range with a 2-year limited warranty, giving reasonable peace of mind for a budget-focused external drive.
