What to Check Before Buying a 8TB External Hard Drive
3.5-inch desktop externals need wall power but cost much less per TB. 2.5-inch portables run off USB but top out around 5TB.
Externals often contain SMR or white-label drives. If you plan to shuck the drive for a NAS, research which model is inside the enclosure first.
USB 3.0 (5 Gbps) saturates any hard drive, so USB-C vs USB-A is about convenience, not speed. Thunderbolt adds nothing for a single HDD.
Ignore it in the price comparison - free tools (or your OS) do the same job.
