Seagate Exos 7E10 4TB enterprise drive

The Seagate Exos 7E10 is a 3.5-inch internal hard drive built for 24x7 enterprise workloads. It delivers 4TB of capacity on a SATA interface with a 7200 RPM spindle and 256MB cache. The drive is rated for a 550TB yearly workload and a 2 million hour MTBF. It suits data centres and bulk storage arrays needing sustained throughput.

12 Gb/s SAS interface with 512N sectors

The single specification that decides fit is the dual-interface design: the drive speaks both 12 Gb/s SAS and SATA 6 Gb/s, and it presents 512-byte native sectors. Controllers or backplanes that require 512e emulation or pure SATA signalling will not match this drive. Verify the host bus adapter and RAID controller support 12 Gb/s SAS and 512N before purchasing.

Enterprise thermal and power profile

Designed for continuous operation in multi-drive chassis, the Exos 7E10 uses rotational vibration safeguards and on-the-fly error correction to maintain consistent performance. PowerChoice technology lets the system tune idle power without sacrificing response time. Acoustic output and thermal load scale with the 7200 RPM spindle under typical RAID workloads.
