Seagate Exos 7E10 8TB 7200 RPM Enterprise Hard Drive

The Seagate Exos 7E10 8TB (ST8000NM017B) is an enterprise-class 3.5-inch internal hard drive engineered for continuous, demanding workloads in cloud data centres, enterprise servers, and storage arrays. Running at 7,200 RPM over a SATA 6 Gb/s interface, it delivers a maximum sustained transfer rate of 255 MB/s from the outer diameter, making it well-suited for sequential read-intensive applications and large-dataset workflows. At the heart of the drive is a 256 MB multi-segmented cache combined with advanced write caching backed by 8 MB of internal NOR flash, helping to smooth bursty I/O patterns. The drive supports both 512e and 4Kn logical sector sizes, preserving compatibility with legacy infrastructure while enabling alignment with modern storage stacks. Seagate’s proven helium side-sealing weld technology is employed for added robustness and leak protection, contributing to the drive’s consistently low idle power draw of approximately 7.06 W average. Under random-read operating conditions, power consumption is rated at approximately 11.03 W, helping data-centre operators manage watts-per-terabyte budgets. The PowerBalance and PowerChoice technologies give administrators additional levers to tune the performance-versus-power trade-off to their specific environment. Enterprise reliability is reinforced by a 2,000,000-hour MTBF rating, an annualised failure rate of 0.44% at full 24/7 operation, and a non-recoverable read error rate of no more than 1 sector per 10^15 bits read. The drive is rated for 8,760 power-on hours per year and tolerates operating shock of 70 G (read) / 40 G (write) at 2 ms. Non-operating shock tolerance reaches 300 G at 2 ms. The Super Parity feature provides an additional layer of data-integrity protection against multi-bit errors. Seagate Secure built-in data protection safeguards stored data in enterprise environments. Low-halogen construction aligns with environmental compliance requirements, and Seagate states the Exos line is built with more renewable energy and recycled materials relative to prior generations.
