160 TB 8-bay NAS with 10 GbE

The Buffalo TeraStation 5020 series TS5820DN16008 is a desktop network-attached storage appliance pre-populated with eight 20 TB NAS-grade drives. A quad-core Annapurna Labs AL524 processor at 2.04 GHz and 8 GB of DDR4 memory drive the system. RAID levels 0, 1, 5, 6, 10 and JBOD are supported and the array ships pre-configured.

Teams needing 10 GbE and cloud sync

Organisations that want a single 10 GbE port plus two 1 GbE links for fast LAN file transfers will fit this unit. Built-in connectors for Amazon S3, Dropbox, Microsoft Azure and OneDrive suit hybrid cloud workflows. Buyers who require more than one 10 GbE port or need a rackmount chassis should evaluate other form factors.

AL524 quad-core with 8 GB DDR4

The Annapurna Labs Alpine AL524 quad-core processor running at 2.04 GHz paired with 8 GB of DDR4 memory determines the throughput ceiling for RAID reconstruction, snapshot operations and concurrent user sessions. This compute and memory combination is the specification that decides whether the appliance matches the workload.
