Manufacturer description
The ADATA HV620S packs 2 TB of storage into a 2.5-inch shell just 11.5mm thick, which is the whole point of this drive: it slides into a jacket pocket or a laptop sleeve without adding a brick to your bag. The SuperSpeed USB 3.1 interface handles large transfers - game libraries, RAW photo archives, project backups - and stays backwards compatible with USB 2.0, so older desktops and consoles still see the drive without an adapter or a separate power supply. ADATA finishes the HV620S with a mirror-like black surface and a raised peripheral lip, a small design touch that keeps the glossy top…
