What owners and reviewers say
Summarised from 2 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Delivers a huge amount of capacity for far less than an equivalent bare internal drive.
- Good value for buyers willing to remove it from the enclosure, with a straightforward layout.
- Owners consider it strong value per terabyte, often buying the largest capacity on sale.
- Empty-drive transfer speeds are reported in the range of roughly 160 to 280 MB/s.
- Owners who opened the enclosure to reuse the drive inside report finding a higher-tier Seagate unit, and praise the retail packaging.
Commonly criticised
- Requires a separate power adapter rather than being bus-powered, and uses an older connector instead of USB-C.
- The enclosure is awkward to open.
- Owners repeatedly report drives failing within a year or two, in several cases including the warranty replacement.
- Owners describe a slow, frustrating warranty process and criticize the one-year warranty.
- Transfer speed is reported to fall as the drive fills.
