12-Bay Rackmount NAS with 48TB Pre-installed

The Buffalo Technology TS51220RH4804 is a 12-bay rackmount network-attached storage system shipped with four 12TB enterprise-grade hard drives pre-configured in RAID. It targets businesses that need immediate, high-capacity shared storage for file serving, backup targets or virtualization workloads without the delay of drive sourcing and array setup.

Sustained Load Behaviour with 16GB DDR4

Sixteen gigabytes of DDR4 memory support the native 10GbE port and multi-protocol file services during continuous read and write streams. The system maintains throughput for concurrent users and virtual machines by keeping hot data in RAM while the four installed drives handle the persistent write path across RAID 0, 1, 5, 6, 10 or JBOD configurations.

Practical Limits of 10GBASE-T and SATA III

The single 10GBASE-T interface tops out at ten gigabits per second over copper cabling up to one hundred metres, so aggregate throughput cannot exceed that ceiling even with faster drives. Each drive bay connects through SATA III at six gigabits per second, which bounds individual drive performance and makes the eight empty bays useful for capacity expansion rather than raw speed gains.
