12-Bay 32TB rackmount NAS with pre-configured RAID

The Buffalo Technology TS51220RH3204 is a 12-bay rackmount network-attached storage device that ships with four 8TB enterprise-grade hard drives pre-installed and RAID pre-configured. It targets businesses that need high read-write performance and immediate deployment without manual drive installation or array setup. The unit includes 16GB of DDR4 memory and an Annapurna Labs Alpine AL524 quad-core processor running at 2.04 GHz.

Dual 10GbE and dual 1GbE ports define network

Network connectivity is limited to two 10GbE RJ-45 ports and two 1GbE RJ-45 ports, supporting IEEE 802.3, 802.3u and 802.3ab standards. No additional network interfaces or higher-speed ports are present, so aggregate bandwidth tops out at the combined capability of these four links. USB expansion is restricted to two USB 3.0 and two USB 2.0 ports for external storage or backup targets.

Eight empty SATA bays limit raw capacity expansion

The chassis provides twelve SATA drive bays but only four are populated with the included 8TB drives, leaving eight bays available for future growth. Maximum raw capacity depends entirely on the drive model specified in the compatibility list (OP-HD8.0H2U-5Y) and the chosen RAID level. Buyers who need more than the factory 32TB must source additional approved drives separately.

Questions about this item

How many drive bays are populated out of the 12 available?

Four bays come filled with 8 TB enterprise drives giving 32 TB usable capacity; the remaining eight bays are empty for future expansion.

What real-world throughput can I expect from the dual 10 GbE ports?

The 10 GbE links can move data at up to 10 Gbps each, so large sequential transfers will saturate a 10 GbE network path while the quad-core AL524 processor and 16 GB DDR4 handle RAID overhead.

Which IEEE Ethernet standards do the RJ-45 ports comply with?

The two 10 GbE and two 1 GbE ports meet IEEE 802.3, 802.3u and 802.3ab, so they negotiate 10 Gbps, 1 Gbps, 100 Mbps or 10 Mbps automatically over standard copper cabling.
