Enterprise capacity and speed

This Seagate Exos 7E8 drive provides 4TB of storage on a SATA 6.0Gb/s interface. It spins at 7200 RPM with a 256MB cache and 4.16ms average latency. The 3.5 inch form factor fits standard enterprise bays. Advanced Write Caching uses 2M internal NOR flash for data integrity.

Suited for array workloads

The drive targets enterprise storage arrays and servers that demand sustained throughput. Humidity Sensor, SuperParity, Low Halogen, PowerChoice and PowerBalance features support dense, always-on deployments. Builders needing a different interface or a smaller physical size should consider other form factors.

SATA 6.0Gb/s interface decides fit

The single specification that determines compatibility is the SATA 6.0Gb/s interface. Your host controller or backplane must provide this exact connection. No other interface option exists on this model, so verify the host side before purchase.
