A 2.5-inch external hard disk can provide that extra storage you need when you're on-the-go. Adata is one of the players in this market, so we tested three of their USB 3.0 DashDrive models with 500 GB of storage, the HV610, HD710 and HE720. Hardware.Info tested them to find out how they perform and what sets them apart. 

Hardware.Info tested the 500 GB version of the Adata DashDrive HV610, available for around £65. Adata also has a 750 GB and a 1 TB version. The HV610 stands out with its unique design. The casing of the hard drive is white, and has a plastic cover shaped like pieces of a puzzle. That cover is available in various colours, and has a slot for storing the USB cable. The HV610 weighs 210 grams, and the casing is fairly resistant to scratches and finger prints.

The Adata DashDrive Durable HD710, available for £67.50, comes in the same capacities as the HV610, but has a very different design. It weighs more at 250 grams, and is larger as well. There is a good reason why Adata added "Durable" to the product name. The black and blue design gives the HD710 a rugged look. The black part has a bit of kevlar pattern, and the rubber strips come in black, blue or orange. The USB cord can be attached to the side of the casing here as well during transportation. The casing is resistant to scratching and dirt.

Lastly there is the £69 DashDrive Elite HE720, which should be the most high-end out of the three judging by the product name. The HE720 is only available in a 500GB version, which looks great thanks to a very stylish design. The external drive is only 9 mm thick. The casing is not entirely straight however, the left corner points upward a little bit which makes it not sit entirely flat on the table. A second test sample has the same issue. The casing is more sensitive to finger prints than the other two drives, and there is no way of attaching the USB cable during transport.
