WD My Book Duo vs NAS – which one is better? The WD My Book is a DAS device, using USB 3.0. It’s designed for a direct connection to a PC/Mac. For a wireless connection is designed the My Cloud, using Ethernet, instead of USB. Usually, there could be the possibility of attaching an external DAS drive via USB to the router to use it as a DIY NAS, but it depends very much on the firmwares, the drive and especially on the router itself. It could in most cases work with a portable external drive, but the My Book is more specific in design, so even if you succeed half way through you could either way encounter problems.
