I bought an ioSafe Duo RAID 1 USB 3.2 Flame/Waterproof Desktop Hard Drive (16 TB (2 x 8 TB)). This is about the fifth ioSafe I've bought, but the first duo. All ioSafe models that I have purchased have worked well and lasted a long time. I only really upgraded when the storage capacity increased. Duo in Raid Mirror mode added another layer of redundancy to my already solid backup routine. So far I've been very happy with the performance and speed of the duo. Highly recommended.
