Ready-to-deploy 8-bay NAS with 64 TB

The Buffalo TeraStation 5020 arrives fully populated with eight 8 TB NAS-grade drives in a desktop chassis. The array is pre-configured in RAID so the unit can serve files immediately after network connection. It targets small-business teams that need secure, high-capacity storage without the delay of drive installation or RAID setup.

Quad-core Alpine AL524 with native 10 GbE

A 2.04 GHz Annapurna Labs processor and 8 GB of DDR4 memory drive the storage engine, while one 10 GbE and two 1 GbE RJ-45 ports handle network traffic. Four USB ports — two USB 3.0 and two USB 2.0 — provide direct-attached expansion or backup targets. The platform supports VMware and Windows Server 2022 certification for virtualisation workloads.

Snapshot backup and cloud-tiering built in

AES-256 volume encryption, two-factor authentication and snapshot technology protect data against ransomware and accidental deletion. Integrated cloud agents connect to Amazon S3, Dropbox, Microsoft Azure and OneDrive for off-site tiering. A remote-management console lets administrators monitor multiple TeraStation units from a single interface.

Domande su questo articolo

How many drives can the 8-bay SATA chassis hold before RAID rebuilds slow down?

The unit ships with eight 8 TB SATA drives filling every bay, giving 64 TB raw capacity under RAID 0, 1, 5, 6, 10 or JBOD.

What is the power draw and resulting heat when the Annapurna AL524 quad-core and eight drives run continuously?

Rated consumption is 112 W from a 100-240 VAC supply, so sustained operation produces heat equivalent to that wattage.

Which network cables and switch ports are needed to use the native 10GbE and dual 1GbE links?

Standard RJ-45 Cat6a or better for the 10GbE port and Cat5e or better for the two 1GbE ports; no SFP+ modules required.
