Those looking after a "reasonable" and safe "redundant" data store has this ICY BOX-a flexible and good solution. I run the box with 2 SATA disks (2 TB each) in a RAID1. Backs up all data of my Dektop, tablets, Smartphone and easy All I want to keep permanently. Over the years there has accumulated a lot. From vacation pictures (digital camera) the last 18 years through data and images of different phones and smartphones incurred over the years through various video clips and images. Fast connection via USB3 and "simple" device, thanks to the understandable manual. Is under my desk and is inaudible. When's the RAID device does not work immediately, there's help in forums. Property already the 2nd ICY BOX at the start with 2 x 1 TB plates as short to medium term memory, since I data loss, can not afford it due to the failure of a disk. Anyone who has ever suffered data loss due to drive crash knows what I'm talking about, or write! Buy recommendation!
