The ADATA HD650 External Hard Drive is back stronger and bigger than before. Its impact-absorbing rubber coating and three-layer construction make it extremely durable to protect your contents, all while looking cool. We now offer it in three colors: blue, black, and red. Capacity goes up to 4TB, a milestone for unpowered external hard drives! With USB 3.2 Gen 1 speeds and ADATA-backed quality, the HD650 delivers spacious and secure storage.

The triple-layer construction of the HD650 incorporates unique silicone material with exceptional elasticity to provide great shock absorption on all axes.
Data fidelity keeps increasing, and files continue to grow. Videos are in 4K and will soon be 8K, games are massive, and on it goes. The time has come for larger drives. We're proud to offer the HD650 in up to 4TB, significantly larger than previous generation external HDDs, with USB 3.2 Gen 1 speeds and no power supply.


The housing is constructed of a durable composite plastic material, highly resistant to scratching and marring.


The SuperSpeed USB 3.2 Gen 1 interface delivers blazing data transfer speed, which can be monitored by the blue LED indicator. The HD650 is fully compatible with Windows 10.x (and earlier) operating systems.
The HD650 can be connected to game consoles and be used as backup storage for games that are not currently being played.

If the hard drive emits metallic clicking sounds and experiences slow read speeds or computer crashes, it is recommended to immediately back up your data, unplug the hard drive's power cable, and send it for repair.
