Manageability: Any device you purchase will have its storage limits so it's common to purchase a number of similar devices. Any money saved by doing so will be sucked down the drain during your first outage. Never cut corners on power supplies or cooling components. Some of the latest devices allow you to install and designate drives and network adapters as hot spares. But you'll be happy you did when one of these replaceable components goes down. Redundancy: You'll pay more for devices with redundant power supplies and cooling fans. If you store your backups offsite, having a NAS with a disk-caddy can make it easy to remove and insert new drives. Most of the newer products make it easy to insert and remove drives. Also consider products that automatically rebuild your RAID array when you add new drives or drives of varying capacity. Most NAS servers support hot-swappable drives. My advice is to purchase twice as much storage as you need today. You'll have to assess the needs of your company. Purchasing a device with a lot of capacity is one option.
