Seagate Exos 7E10 4TB 3.5" 7200RPM SAS Internal HDD

The Seagate ST4000NM025B is a 4TB Exos 7E10 internal hard drive that delivers high throughput while maintaining dependable operation for servers, storage arrays, and other enterprise systems. It installs in a standard 3.5 inch bay and connects through a SAS 12 Gb/s interface, giving administrators a straightforward way to add capacity without compromising speed.

A 7200 RPM spindle works with a 256 MB cache to keep I/O queues moving, so virtual machines boot promptly, databases respond quickly, and backup windows remain short. Whether you are expanding a cloud node, building a surveillance archive, or outfitting a file server, the drive supplies consistent, predictable performance.

The design targets continuous round-the-clock operation. Seagate rates the drive for a two million hour MTBF and equips it with rotational vibration sensors that help maintain stability in multi-drive enclosures. Active power draw averages 10.3 watts and drops to 5.9 watts at idle, allowing dense deployments without excessive energy use.

IT managers who need a balanced mix of capacity, performance, and durability will find this model well suited to data centers, SAN environments, and enterprise NAS systems. Use it to replace aging drives, build out new storage tiers, or create a reliable destination for high-priority backups.
