Measuring in at just 10.3 mm (19 mm for the 4 TB and 5 TB variants) thick the ADATA HV300 external hard drive is as thin as they come. It slips easily into the pockets of briefcases and backpacks, making it ideal for people on the move. On the inside, it packs up to 5 TB of storage, so it’s got plenty of space for all your media and everything else. With four colors to choose from - black, red, white and blue - there is a color to suit just about any personality. What’s more, it has an elegant design that is guaranteed to impress, namely its eye-catching, glossy front cover surrounded by a beautifully textured frame. Lesser external drives continue to work even when dropped or encounter a shock, resulting in errors and bad sectors. With ADATA’s proprietary shock sensors, all drive activity will cease when a physical shock is detected. Once in the clear, activity resumes. You're kept fully informed with a clear status indicator.
