NAS - 1 to 2 HDD Bays (Ex HDD)
These small-scale NAS units hold one or two HDDs. While this does limit their storage capacity a little, it also keeps their size and cost down. There are options for personal and family home use with user-friendly set-ups as well as for business users in a small or home office environment with more advanced features and greater processing power. 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.
