Seagate TechSource Constellation ES.3 ST4000NM0023 - 4 TB 3.5" Internal HDD - SAS 6Gb/s - 7200 rpm - 128 MB

Built for enterprise scale, the Seagate TechSource Constellation ES.3 ST4000NM0023 is a 4 TB, 3.5" internal hard drive that combines SAS 6Gb/s connectivity with a 7200 rpm spindle speed and a 128 MB buffer. This large-form-factor drive addresses heavy data growth demands and is engineered for 24x7 operation using sixth-generation drive technology with support for both SAS and SATA interfaces. Data integrity is reinforced by enhanced error correction, super parity and end-to-end SAS-based safeguards to ensure accurate storage. The drive delivers steady performance under load thanks to high rotational vibration tolerance. Power and thermal efficiency are improved through low power draw and on-demand PowerChoice technology, compliant with T10/T13 power management standards. Enterprise RAID readiness is enhanced by multi-drive firmware designed for maximum system availability, while performance features such as dual processors, ramp load technology, a top-cover-attached motor and a humidity sensor help maintain optimal operation across chassis. For secure data retirement and protection of data at rest, the unit is a self-encrypting drive (AES-256) with FIPS 140-2 validation and supports Seagate Instant Secure Erase to reduce IT disposal costs.
