Buffalo Technology TS5420RN1604 16TB 4-Bay Rackmount NAS

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.
