5+ Drive Bay Desktop Network Attached Storage Systems

These NAS units are the largest around, offering five HDD bays at a minimum and ten or more in many cases. They are typically geared towards advanced users who need plenty of storage space, and many are supplied in rackmount cases for use in industry and large-scale businesses. These units are not sold with hard disks so you'll need to add your own – it's best to get matching models and capacities, especially if you plan on using RAID.
