Spare drive for TeraStation 51210RH

This 16 TB hard drive is a factory spare for the TeraStation 51210RH desktop NAS. It arrives new and ready to install in a compatible enclosure. The unit is intended for administrators who need to replace a failed disk or expand an existing array without sourcing a third-party drive.

Sustained operation in a RAID array

Designed for continuous duty inside a multi-bay NAS, the drive handles the steady read and write streams typical of RAID rebuilds and daily file serving. Its firmware is tuned for the TeraStation platform, so rebuild times stay predictable even when the array is under heavy load for extended periods.

Thermal and acoustic profile in a 1.06" bay

The 1.06" high form factor fits the standard drive tray, allowing the NAS chassis to manage airflow across all installed disks. At 1.70 lbs the drive adds minimal mass, and power draw remains within the enclosure's rated supply limits so fan speeds stay low during normal file-access workloads.
