Great product. 1) It works. 2) Transfer speeds are outstanding. 3) It was simple plug and play, with Windows 10 recognizing drives immediately. 4) It is very intelligently designed. The open design allows the drives to run cool - even cooler than the internal drives being "cooled" by fans. Hard drives run hot. Full enclosures cause hard drives used as externals to fail as they simply run excessively hot. This design is great. Also, the design allows for easy switch out of drives. I bought two - and they both work great.
