Seagate Constellation 3TB 3.5" 7200RPM SAS 6Gb/s Enterprise Internal HDD

The Seagate ST33000650SS is an enterprise hard drive designed for servers that need dependable capacity, strong throughput, and nonstop availability. This 3.5-inch model provides 3 TB of storage and connects through a 6 Gb/s Serial Attached SCSI interface.

With a spindle speed of 7200 rpm, a 64 MB cache, and a sustained transfer rate of up to 155 MB per second, the drive keeps databases, virtual machines, and analytics tasks running smoothly. Dual SAS ports allow redundant paths for failover or shared access between controllers, while the interface can deliver up to 600 MB per second on the external link.

Seagate rates the drive for 1.2 million hours mean time between failures and supports round-the-clock duty cycles. Built-in power management helps control energy costs, and the five-year limited warranty adds confidence for long deployments.

The drive fits any standard 3.5-inch SAS bay, making it an easy drop-in replacement or expansion choice for rack servers, storage arrays, and backup appliances. Administrators in data centers, small business server rooms, and test labs can rely on the consistent throughput when running virtualization clusters, file shares, or streaming backup jobs.
