"Drobo's 5N2 combines their long-standing tradition of dead simple setup and configuration with increased speed through a pair of bonded Gigabit Ethernet interfaces. Bonding takes the 5N2 from a device that can perform solidly on two separate networks to one that can offer almost twice the performance on a single subnet. While Drobo increased the processing capability to support the additional network throughput, we were beginning to encroach upon the seek performance of NAS-grade HDDs when attempting to serve two simultaneous Gigabit streams. DroboApps has grown to cover the majority of things you would possibly want to run on a home NAS, and DroboDR offers off-site backup (to another Drobo). Overall, the combination of Drobo's BeyondRAID, bonded Gigabit Ethernet, 5 drive bays, and a competitive price point, make for a compelling NAS package worthy of serious consideration for any home or small business network storage needs."
