Enterprise 3TB SAS Drive

This Toshiba MG03SCA300 is a 3.5 inch internal hard drive with a 6Gb/s SAS interface, 7200 RPM spindle speed and 64MB cache. It is built for 24 x 7 operation in nearline enterprise storage arrays and servers that require a SAS host connection.

Suits RAID arrays and backup appliances

The drive targets administrators who need high-capacity mechanical storage with rotational vibration tolerance for multi-drive chassis and enhanced power condition state technology for efficient idle periods. It is not suited for systems without a SAS controller, nor for buyers who need solid-state latency, larger capacities than 3TB, or a 2.5 inch form factor.

Interface decides compatibility

The single specification that determines fit is the 6Gb/s SAS interface; the host must provide a matching SAS port and cable, otherwise the drive cannot communicate with the system.
