A mutually supported file system and clean ejection reduce avoidable compatibility and corruption problems. Treat exFAT where large cross-platform files are required as the practical test.
Bundled encryption applications can depend on a supported operating system and may not run on televisions, phones or managed computers. Compare recovery access on every system that must open the files across the available options.
A fake drive can report 256GB while silently overwriting data once its smaller physical memory fills. Resolve testing the full capacity with a reputable verification tool before checkout.
A protected connector, solid keyring point and minimal moving parts reduce everyday mechanical exposure. Factor in cap retention and housing strength as well as appearance when judging value.
Dual plugs are useful when files regularly move between older computers and current phones or thin laptops. Verify both interfaces and their rated transfer speeds on the exact SKU.
