BUFFALO TS5820DN8004 – TeraStation 5020 80TB 8-Bay 10GbE NAS
Overview
The BUFFALO TS5820DN8004 is a TeraStation 5020 Series 8-bay desktop NAS configured with 80TB of installed storage using four 20TB NAS-grade CMR hard drives. The chassis provides four additional drive bays for expansion and supports RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and JBOD configurations.
The TS5820DN8004 is designed for business environments requiring centralized network storage, high-capacity disk configurations, and high-speed Ethernet connectivity. Its eight-bay desktop chassis combines a 10GbE interface with two additional 1GbE ports for deployment across mixed-speed network infrastructure.
Technical Information
The system uses an Annapurna Labs Alpine AL524 processor operating at 2.04GHz with four CPU cores and 8GB of DDR4 memory. The included NAS-grade hard drives use SATA storage interfaces, while the platform provides two USB 3.2 ports and two USB 2.0 ports for supported peripherals.
Network connectivity consists of one 10GbE RJ-45 port and two 1GbE RJ-45 ports. Network services include TCP/IP, CIFS/SMB, AFP, FTP/FTPS/SFTP, and NFS.
The TS5820DN platform supports snapshots, remote configuration, and abnormal file activity detection. Buffalo also specifies hot-swapping and hot-spare support for the eight-bay platform.
Compatibility
The TS5820DN8004 is intended for Ethernet-based NAS environments and supports 10GbE and Gigabit Ethernet connectivity through RJ-45 interfaces. The system supports Windows and macOS client environments listed by Buffalo for the TeraStation 5020 platform.
Supported storage configurations include RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and JBOD. Four of the eight drive bays are populated in the TS5820DN8004, leaving four bays available for compatible additional drives.
Buffalo identifies the TS5820DN platform as using NAS-grade CMR hard drives. Compatible replacement and expansion drives should be selected from Buffalo-supported drive options rather than assuming that any third-party HDD is supported.
