4-Bay Desktop NAS with 8 TB Storage

The Buffalo TeraStation 5420 delivers a pre-populated 8 TB desktop NAS using two 4 TB NAS-grade drives. A quad-core Annapurna Labs AL524 processor running at 2.04 GHz and 8 GB of DDR4 memory power the unit for small-business file sharing and backup workloads.

Sustained Load Behaviour

RAID levels 0, 1, 5, 6, 10 and JBOD are pre-configured so data protection begins immediately. The AL524 quad-core architecture maintains throughput during concurrent multi-user access while snapshot technology provides near-instantaneous backup and recovery without interrupting ongoing transfers.

10GbE and USB Interface Limits

A single native 10GbE RJ-45 port alongside two 1 GbE ports handles high-speed file transfers over existing cabling. Two USB 3.0 and two USB 2.0 ports allow direct-attached expansion or printer sharing. Cloud integration with Amazon S3, Dropbox, Azure and OneDrive extends the storage boundary beyond the local network.
