BUFFALO TS5420RN3204 – TeraStation 5020 32TB 4-Bay 1U Rackmount NAS
Overview
The BUFFALO TS5420RN3204 is a TeraStation 5020 Series 4-bay rackmount NAS configured with four 8TB NAS-dedicated HDDs for 32TB of total installed raw storage. Its 1U rackmount chassis provides centralized network storage for business file sharing, backup, data protection, and rack-based NAS deployments. The system provides one 10GbE port and two 1GbE ports for integration into multi-gigabit Ethernet environments.
Technical Information
The TS5420RN3204 uses an Annapurna Labs Alpine AL524 2.0GHz quad-core 64-bit processor with 8GB DDR4 ECC memory. Storage supports RAID 0, 1, 5, 6, 10, and JBOD. Buffalo specifies RAID 6 as the factory configuration; with the installed 32TB raw capacity, RAID 6 provides 16TB of effective capacity.
The TeraStation 5020 platform supports snapshots, abnormal file activity detection, remote configuration, hot swapping, and hot spares. The TS5420RN platform does not support SSD caching. Network file services include CIFS/SMB, AFP, FTP/FTPS/SFTP, and NFS.
Compatibility
The TS5420RN3204 uses four 3.5-inch NAS-dedicated HDDs with SATA III interfaces supporting up to 6Gbps. All four drive bays are populated in this configuration.
Network connectivity consists of one 10GBASE-T RJ-45 port and two 1000BASE-T RJ-45 ports. The 10GbE interface supports 10Gbps, 5Gbps, 2.5Gbps, and 1Gbps operation, while the 1GbE ports support 1000Mbps, 100Mbps, and 10Mbps operation. Supported network file services include CIFS/SMB, AFP, FTP/FTPS/SFTP, and NFS.
Key Features
- 32TB installed capacity using four 8TB NAS-dedicated HDDs
- 4-bay 1U rackmount chassis with all four drive bays populated
