Capacity and purpose

The Seagate Exos 7E10 ST4000NM024B is a 4TB 3.5 inch enterprise hard drive built for 247 bulk data workloads. It suits data-centre architects and IT professionals who need high-capacity, cost-effective storage for unstructured data in servers or storage arrays. Buyers who want a desktop drive for light client workloads should consider a different product line.

Host interface and power

The drive connects through a SATA 6.0Gb/s interface and requires a standard SATA data cable plus a SATA power connector from the host system. Verify that your backplane or controller supports 3.5 inch SATA drives and that the chassis provides adequate drive bays and cooling airflow for continuous operation.

Thermals and acoustics

Rated for 247 enterprise duty, the drive is engineered to sustain 550 TB per year workloads with a 2 million hour MTBF. In normal multi-drive arrays the 7200 RPM spindle produces typical enterprise-level acoustics and heat; plan for sufficient chassis ventilation to maintain reliable temperatures under sustained write loads.
