BUFFALO TS51220RH3204 – TeraStation 5020 32TB 12-Bay 2U Rackmount NAS
Overview
The BUFFALO TS51220RH3204 is a TeraStation 5020 Series 2U rackmount NAS with 12 drive bays and four installed 8TB enterprise-grade HDDs, providing 32TB of total raw storage. Eight drive bays remain available for future expansion. The system is designed for business and enterprise rack environments requiring centralized network storage, redundant storage configurations, and 10GbE connectivity.
Technical Information
The TS51220RH3204 uses an Annapurna Labs Alpine AL524 2.04GHz quad-core processor with 16GB DDR4 ECC memory. Its software RAID implementation supports RAID 0, 1, 5, 6, 10, and JBOD. RAID 6 is the factory configuration, providing 16TB of effective capacity from the installed 32TB raw storage.
The platform includes RAID acceleration, metadata duplication, copy-on-write, snapshots, immutable snapshots, scheduled and snapshot-based backup, replication, failover, abnormal file activity detection and protection, iSCSI volume backup, cloud-storage integration, and remote configuration through Buffalo KikiNavi services.
Compatibility
The TS51220RH3204 uses 3.5-inch enterprise-grade HDDs with SATA 6Gbps interfaces. Buffalo identifies the OP-HD8.0H2U-5Y 8TB replacement drive as compatible with this exact model. The chassis provides 12 drive bays, with four occupied by the factory-installed drives.
Network connectivity includes two 10GBASE-T ports and two 1000BASE-T ports using RJ-45 interfaces. The system supports IEEE 802.3ad Link Aggregation, IEEE 802.3x Flow Control, 10GBASE-T, 5GBASE-T, 2.5GBASE-T, 1000BASE-T, 100BASE-TX, and 10BASE-T on the applicable interfaces.
Key Features
- 32TB total storage using four 8TB enterprise-grade HDDs
- 12-bay 2U rackmount chassis with eight available drive slots
- 2 x 10GBASE-T and 2 x 1000BASE-T network interfaces
- 16GB DDR4 ECC memory with AL524 2.04GHz quad-core processor
- RAID 0/1/5/6/10/JBOD with RAID 6 configured at shipment
Applications
The TS51220RH3204 is suited to rack-based business file storage, centralized data repositories, backup infrastructure, shared network storage, virtualization-related storage workloads, and deployments where additional drive bays are required for future capacity expansion.
DC Supplies Product Note
This exact TS51220RH3204 configuration includes four 8TB enterprise-grade HDDs in a 12-bay chassis, leaving eight drive slots available. The factory RAID 6 configuration provides 16TB of effective capacity from the 32TB installed raw capacity.
