BUFFALO TS5820DN3204 – TeraStation 5020 32TB 8-Bay 10GbE Desktop NAS
Overview
The BUFFALO TS5820DN3204 is a TeraStation 5020 Series 8-bay desktop NAS configured with four 8TB NAS-grade CMR hard drives for 32TB of installed storage. Four additional drive bays remain available for future capacity expansion. The system combines 10GbE connectivity with two additional 1GbE ports and is designed for business file storage, backup, data protection, and shared network storage.
Technical Information
The TS5820DN3204 uses an Annapurna Labs Alpine AL524 2.04 GHz quad-core processor and 8GB of DDR4 memory. Its storage architecture supports RAID 0, 1, 5, 6, 10, and JBOD configurations, with hot-swappable drives and hot-spare support. Buffalo specifies snapshots, abnormal file activity detection, and remote configuration for the TeraStation 5020 platform. The installed configuration contains four 8TB NAS-grade CMR HDDs for 32TB of native capacity.
Network connectivity includes one 10GbE RJ-45 interface and two 1GbE RJ-45 interfaces. The 10GbE interface supports 10GbE, 5GbE, 2.5GbE, 1GbE, and 100MbE/10MbE Ethernet operation. Network file services include CIFS/SMB, AFP, FTP/FTPS/SFTP, and NFS, while iSCSI support is also documented by enterprise distribution sources for this exact MPN.
Compatibility
The TS5820DN3204 uses 3.5-inch SATA storage and is supplied with four 8TB NAS-grade HDDs. The chassis provides eight total drive bays, leaving four bays open for additional compatible drives. Buffalo identifies the platform as supporting RAID 0/1/5/6/10/JBOD and hot-swappable drive operation.
The network interfaces use RJ-45 connections, allowing the NAS to connect directly to 10GbE and Gigabit Ethernet infrastructure. Supported network services include SMB/CIFS, AFP, FTP, FTPS, SFTP, and NFS. The system operates from an internal 100–240V AC, 50/60Hz power supply.
