Capacity and interface

The Seagate Constellation ES.3 is a 2TB 3.5-inch internal hard drive with a SATA 6Gb/s interface and 128MB cache. It spins at 7200RPM and is built for desktop systems that need high-capacity bulk storage.

Thermals, noise and power

Normal desktop operation keeps the drive within its standard thermal envelope using the system's existing airflow. The 7200RPM spindle produces typical mechanical noise levels for this class of drive. Power draw follows the SATA specification for 3.5-inch units under read, write and idle loads.

Questions about this item

How is the 3.5-inch SATA drive installed in a desktop, and what step do people often miss?

Mount the drive in a 3.5-inch bay using four screws, connect the SATA data cable to the motherboard and the SATA power cable from the PSU, then enable the SATA port in BIOS so the 2TB volume appears.

What maintenance or replacement will the 7200RPM Constellation ES.3 need later?

No scheduled maintenance is required; monitor SMART attributes for reallocated sectors and replace the drive if the health status degrades or after the rated workload limit is reached.
