Enterprise storage drive

The Seagate Exos 7E8 ST2000NM003A is a 2TB 3.5 inch internal hard drive built for enterprise bulk data applications. It uses conventional magnetic recording technology and spins at 7200 RPM with a 256MB cache to deliver reliable performance for 247 operations.

SAS 12Gb/s integration

This drive connects via a SAS 12Gb/s interface and requires a compatible SAS controller or backplane in the host system. The 3.5 inch form factor fits standard enterprise drive bays while the bare drive packaging means no cables or mounting hardware are included in the box.

Bare drive packaging

The product ships as a bare drive without retail accessories, software utilities or mounting screws. System integrators must supply their own rails, cables and management tools to deploy the drive in a server or storage array.

Questions about this item

What sustained-transfer limit appears first when the Exos 7E8 runs at full tilt?

The SAS 12Gb/s interface caps sustained throughput, so the drive cannot push data faster than the 12Gb/s link allows.

How much heat and noise should I expect from the 3.5" 7200 RPM drive in 247 operation?

The 3.5" 7200 RPM mechanical design produces typical enterprise drive acoustics and heat; a chassis with active airflow is recommended for continuous 247 use.

Which host connector must my system already provide for this SAS 12Gb/s drive?

The drive requires a SAS 12Gb/s port on a host bus adapter or backplane; without that specific SAS connection the drive will not operate.
