2 TB SATA Internal Drive

The Buffalo Technology OP-HD2.0ZS-3Y is a 2 TB internal hard drive built for desktop and server installations. It connects through a standard SATA interface rated at 600 MB/s with a 7-pin connector. The unit measures 1.2 inches high by 4.1 inches wide by 6.7 inches deep. A three-year limited warranty covers the drive.

Suited for TeraStation NAS upgrades

This drive matches the Buffalo TeraStation TS-2RZSD NAS server and serves as a direct replacement for the 7210R model. It fits buyers who need a compatible spare or capacity refresh for that specific platform. Builders requiring a different form factor or a non-SATA interface should look at other options.

SATA/600 interface decides fit

The single specification that determines compatibility is the SATA/600 interface with a 7-pin connection. Your system or enclosure must provide a matching SATA data and power connector. Without that interface the drive cannot be installed or recognised.
