BUFFALO TS5420RN8004 – TeraStation 5420 80TB 4-Bay 1U Rackmount NAS
Overview
The BUFFALO TS5420RN8004 is a TeraStation 5420 Series business NAS with a 1U rackmount chassis, four 3.5-inch drive bays, and 80TB of installed storage using four 20TB NAS-dedicated hard drives. It provides 1 x 10GbE and 2 x 1GbE network interfaces for centralized file storage, backup, and network data services in rack-mounted IT environments.
Technical Information
The TS5420RN8004 uses an Annapurna Labs Alpine AL524 2.04GHz quad-core 64-bit processor and 8GB DDR4 ECC memory. Storage is managed through software RAID with support for RAID 0, 1, 5, 6, 10, and JBOD. The factory configuration is RAID 6, providing 40TB of effective capacity from the installed 80TB raw storage.
The system supports snapshots, copy-on-write, metadata duplication, backup functions, replication, failover, abnormal file activity detection and protection, remote management through KikiNavi, cloud backup integration, Active Directory integration, two-factor authentication, hot spares, and hot-swappable drives.
Compatibility
The TS5420RN8004 uses four 3.5-inch NAS-dedicated HDDs and provides RJ-45 network connectivity through one 10GBASE-T port and two 1000BASE-T ports. Supported network file services include CIFS/SMB, AFP, FTP/FTPS/SFTP, and NFS, with TCP/IP network support. The system also provides two USB 3.0 ports and two USB 2.0 ports.
The 10GBASE-T interface supports high-speed Ethernet connectivity, while the two 1GbE ports can be used for additional network connections and supported link aggregation or NIC teaming functions. RAID configuration should be selected according to the required capacity, redundancy, and storage architecture.
Key Features
- 80TB installed capacity using four 20TB NAS-dedicated HDDs
- 1U rackmount chassis with four 3.5-inch drive bays
- 1 x 10GbE plus 2 x 1GbE RJ-45 network interfaces
