Ready-to-deploy 16 TB rackmount NAS

This Buffalo TeraStation 5420 ships with four 4 TB NAS-grade drives pre-installed and RAID pre-configured, so the 16 TB capacity is available immediately. The Annapurna Labs Alpine AL524 quad-core processor at 2.04 GHz and 8 GB of DDR4 memory handle high read/write workloads. A native 10 GbE port plus two 1 GbE ports provide flexible network connectivity. The unit fits a standard rackmount footprint and operates from 100-240 VAC power.

Suited for small businesses needing certified

VMware and Windows Server 2022 certification make this NAS a fit for virtualised environments, while AES-256 encryption, two-factor authentication and snapshot backup address strict security requirements. Cloud integration with Amazon S3, Dropbox, Microsoft Azure and OneDrive supports hybrid workflows. Buyers who need more than four drive bays or a desktop form factor should look at other models.

Four-bay SATA chassis defines expansion limits

The enclosure provides exactly four SATA drive bays populated with the included OP-HD4.0N drives, so total raw capacity cannot exceed 16 TB without replacing drives. RAID 0, 1, 5, 6, 10 and JBOD modes are supported for redundancy or performance tuning. Two USB 3.0 and two USB 2.0 ports allow external backup or peripheral attachment.

Perguntas sobre este artigo

How loud or hot does the 4-bay rackmount NAS get when running 24/7 at its 62.85W power draw?

The unit operates at 62.85W within a 0°C to 40°C range and 0-80% non-condensing humidity, designed for continuous business workloads in a standard rack environment.

What drives or accessories must I already own to use the TS5420RN1604 out of the box?

Nothing extra is required; four 4TB NAS-grade SATA drives are pre-installed and the RAID array is pre-configured, so the 16TB system is ready for network connection immediately.

Will my existing 1GbE switches and Cat5e cabling work with the native 10GbE port on this NAS?

Yes, the 10GbE RJ-45 port is backward compatible with 1GbE and 100MbE links, and the two additional 1GbE ports connect directly to your current copper infrastructure.
