The 1TB Constellation.2 SAS 2.5" Internal Hard Drive with FIPS 140-2 Secure Encryption (OEM) from Seagate is a high-performance high-capacity data storage drive that has been designed for environments such engineering workstations, network servers, mainframes, and supercomputers. It is also well-suited for storage-hungry business applications, storage area networks (SAN) and network-attached storage (NAS), maximum-capacity servers and blade servers, rich-media-content storage, enterprise backup and restore (D2D, virtual tape), and cloud computing.

This 2.5" drive is 15mm high and features a 1TB capacity with a SAS 6 Gb/s interface that provides maximum sustained data transfer rates of up to 115 MB/s. Its 6 Gb/s SAS interface is also backwards compatible with SAS 3 Gb/s and SAS 1.5 Gb/s. Rated for Enterprise-class, 24x7 / 8,760 hours per year of operation, the Constellation.2 also features a rotational speed of 7200 rpm which will allow quick access to your data. A 64MB cache will help to ensure uninterrupted data transfers and the drive's 1.4 million hours MTBF combined with its AFR of 0.62% and non-recoverable read error rate of 1 sector per 1015 will help to ensure that this drive has a strong operational life. Regarding data security, this drive is FIPS 140-2 validated and helps to protect sensitive but unclassified and protected class data.

Constellation.2 drives further help to enhance durability by using a dedicated load/unload zone at the outermost radius of the media to help eliminate the possibility of destroying or degrading data by landing in the data zone. The heads automatically go to the ramp load/unload when power is removed from the drove. Furthermore, an automatic shipping lock helps prevent potential damage to the heads and discs that results from movement during shipping and handling. The shipping lock disengages and the head load process begins when power is applied to the drive.

Constellation.2 drives also decode track 0 location data from the servo data embedded on each surface to help eliminate mechanical transducer adjustments and other reliability concerns. The drive also uses a high-performance actuator assembly with a low-inertia, balanced, patented, and straight-arm design that helps to provide strong performance with minimal power dissipation.
