Seagate Business Storage 2-bay 6TB review
 

You get USB 3.0 in the front and back, a solid build quality, good trays for the disks and even a slot for a USM hard disk. It's really a distinguishing factor, and if you need a business-oriented NAS that will only be used for back-ups, then the Seagate Business Storage 2-bay is an interesting option. USM disks can be used in the same manner as tapes, and thanks to the SATA port it's fast. It's also very user-friendly, and using this NAS for making back-ups doesn't require a degree in IT.
