Hoping to drive small and medium business sales, NAS-makers have been pushing to deliver enterprise features such as cloud storage, virtualization support, automated backup software and iSCSI support. There's also been an effort to include technologies such as Link Aggregation, which can increase network bandwidth when dealing with multiple users and also provides redundancy in case one of the links fails.

First seen over a decade ago, 10GbE is not a new technology, but it's been largely reserved for pricey enterprise devices. It's ten times faster than Gigabit Ethernet and only supports full duplex point to point links, which are generally connected by network switches, so 10GbE hubs don't exist.

The 10GbE standard is slowly gaining momentum. With that in mind, we're checking out two new high-end SMB NAS devices: the QNAP TS-879 Pro, which costs $2,200 without its optional 10GbE network card, and the $3,500 Synology DS3612xs.
