Enterprise storage drive

The Seagate Constellation.2 ST91000640SS is a 1TB 2.5-inch SAS hard drive spinning at 7200RPM for enterprise storage arrays. It targets system integrators who need high-capacity 6Gbps SAS storage in a compact form factor.

Sustained workload behaviour

The 7200RPM spindle delivers consistent throughput for sequential workloads such as backup, archiving and video surveillance recording. Rotational latency remains stable during extended writes, avoiding the performance drops seen in lower-speed drives.

SAS 6Gbps interface limits

The 6Gbps SAS link caps maximum burst transfer at the interface rate, while sustained throughput is governed by the mechanical media. Dual-port SAS provides path redundancy but does not increase single-stream bandwidth beyond the 6Gbps ceiling.
