WD My Cloud EX2 Diskless Network Attached Storage - WDBVKW0000NCH-NESN
This is a nice, budget-friendly NAS, but it just lacks anything to really push it beyond comparable models out there. It is a diskless model, so you need your own storage, though if you have more money to spend, then you can choose between several options that come with drives from Western Digital. You get two bays, but they are designed only to fit 3.5 inch drives without adapters to insert 2.5 inch drives which limits the types of hard drives you can use and pretty much eliminates using solid state drives. This model has 512MB of memory and a 1.2GHz processor, but that's not particularly exceptional. You only get two USB ports on this one, but they are both USB 3.0 ports, and a Gigabit Ethernet port, which is good but not any better than what you can find on comparable models.
