BUFFALO TS51220RH12012 – TeraStation 51220RH 120TB 12-Bay 2U Rackmount NAS
Overview
The BUFFALO TS51220RH12012 is a TeraStation 51220RH enterprise rackmount NAS with 120TB of installed storage across twelve 10TB enterprise-grade CMR hard drives. The 12-bay 2U platform provides dual 10GbE, dual Gigabit Ethernet, 16GB DDR4 memory, hardware-compatible hot-swappable drive bays, and multiple RAID configurations for business storage environments.
The twelve installed drives are factory-configured in RAID 6. With 120TB of raw installed capacity, RAID 6 provides 100TB of available capacity according to Buffalo's RAID capacity table. RAID 5, RAID 10, RAID 1, RAID 0, and JBOD are also supported.
Technical Information
The TS51220RH12012 uses an Annapurna Labs Alpine V2 AL524 quad-core processor operating at 2.0GHz and 16GB of DDR4 ECC memory. Storage uses twelve 3.5-inch nearline enterprise drives connected through SATA 6Gbps interfaces.
Network connectivity includes two 10GBASE-T RJ-45 ports and two 1000BASE-T RJ-45 ports. The 10GbE interfaces support 10GbE, 5GbE, and 2.5GbE operation, while the Gigabit interfaces support 1000BASE-T, 100BASE-TX, and 10BASE-T operation where specified by the respective interface.
The chassis provides two USB 3.2 Gen 1 Type-A ports and two USB 2.0 Type-A ports. The platform supports network storage protocols including SMB/CIFS, AFP, FTP, FTPS, SFTP, NFS, TCP/IP, and iSCSI.
Compatibility
The TS51220RH12012 is designed for rackmount infrastructure and supports 12 installed 3.5-inch drives. Buffalo specifies enterprise-grade CMR HDDs for the TS51220RH family, with hot swapping and hot-spare functionality supported.
Supported RAID levels are RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and JBOD. The factory RAID 6 configuration provides dual-drive parity protection and 100TB of available capacity from the 120TB raw installation.
Buffalo lists compatibility with Windows 11, Windows 10, Windows Server 2022, Windows Server 2019, and macOS 10.13 or later. The system is also TAA compliant and manufactured in Japan.
