Mini Hard Drive to me highly recommended by users 'You Tube' and although not knowing the brand, I tried it! Result from + 24 months of use, not a BUG, a reading / quick check of my hyper Doc / Music. I save everything directly on this mini-disc. As big as a credit card, it is surrounded by a protective foam (do not try to remove it like me ... lol) and competes directly with USB keys 256GB Kensington / Patriot / Corsair worth a fortune to 1.5 cm longer! Without ventillateur, no noise or heat! HIGHLY recommend: o)
