BUFFALO TS5820DN9608 – TeraStation 5020 96TB 8-Bay 10GbE NAS
Overview
The BUFFALO TS5820DN9608 is an 8-bay desktop NAS in the TeraStation 5020 series, configured with eight 12TB NAS-dedicated hard drives for 96TB of total installed capacity. It is designed for business storage environments requiring centralized network file services, RAID protection, 10GbE connectivity, snapshots, and scalable storage in a desktop chassis.
Technical Information
The TS5820DN9608 uses an Annapurna Labs Alpine AL524 quad-core 64-bit processor operating at 2.0GHz with 8GB of DDR4 ECC memory. The eight 3.5-inch SATA drive bays are populated with NAS-dedicated hard drives and support software RAID configurations including RAID 6, RAID 5, RAID 10, RAID 1, and RAID 0. RAID 6 is the factory configuration.
Network connectivity consists of one 10GBASE-T RJ-45 port and two 1000BASE-T RJ-45 ports. The 10GbE interface supports 10Gbps, 5Gbps, and 2.5Gbps operation, while the Gigabit Ethernet interfaces support 1000Mbps, 100Mbps, and 10Mbps connectivity.
The system provides firmware redundancy using HDD and NAND flash storage and includes snapshot, copy-on-write, metadata duplication, iSCSI volume backup, scheduled backup, replication, failover, and abnormal file-operation detection capabilities. An optional virus-checking extension is also supported.
Compatibility
The TS5820DN9608 is designed for standard Ethernet storage environments using RJ-45 network infrastructure. Its 10GBASE-T interface can connect to compatible 10GbE copper switches, while the two 1000BASE-T ports provide conventional Gigabit Ethernet connectivity.
The system uses eight 3.5-inch SATA drives and supports RAID 6, RAID 5, RAID 10, RAID 1, and RAID 0. Buffalo specifies 72TB of effective capacity in the factory RAID 6 configuration, with 84TB available in RAID 5, 48TB in RAID 10, 12TB in RAID 1, and 96TB in RAID 0.
