QNAP TS-231+ 2-bay NAS
While QNAP might not be as well known a manufacturer as companies like Western Digital or Netgear, the excellent design and hardware in this budget NAS are undeniable. It has two bays that work with both 3.5 and 2.5 inch drives, giving you support for hard disk drives and solid state drives. You get 512MB of memory in this model along with a 1.2GHz dual-core processor which keeps your data access nice and fast. Connectivity is really a major feature on this model which includes three USB 3.0 ports and two Gigabit Ethernet ports. There is also an eSATA port on this NAS, which lets you connect an external SATA hard drive to it for even more storage than you can fit into this model. All of this comes together to make a terrific NAS that can fit into just about any budget.
