1 TB enterprise SATA drive

The Seagate Exos 7E2 ST1000NM0008 is a 1 TB 3.5-inch internal hard drive built for 24x7 enterprise workloads. It spins at 7200 RPM with a 128 MB cache and uses ninth-generation CMR technology. The SATA 6.0Gb/s interface fits standard 512-native infrastructures and replicated or RAID multi-drive systems. It is engineered for 550 TB per year of data transfer.

Verify SATA power and mounting

Before ordering confirm that your chassis has a free 3.5-inch bay with 26.10 mm height clearance and SATA data plus power connectors. The drive requires a 6.0Gb/s SATA port on the controller or motherboard for full throughput. Ensure your RAID or HBA firmware supports 512-native sector formatting. No additional drivers are needed for basic operation.

On-the-fly error correction and PowerChoice

The bundled firmware includes on-the-fly error-correction algorithms that protect data integrity during heavy write cycles. PowerChoice technology lets the host request lower power states when the drive is idle reducing overall system consumption. Rotational vibration safeguards maintain consistent performance in dense multi-drive enclosures. RAID Rebuild assistance accelerates recovery in redundant arrays.

Questions about this item

Does the Exos 7E2 ST1000NM0008 ship with mounting screws or a SATA data cable, or must I source them separately?

The drive is supplied as a bare 3.5-inch unit; mounting screws and a SATA 6.0Gb/s data cable are not included and must be purchased separately if your chassis or controller does not already provide them.

I see the Exos 7E2 line includes 1TB and 2TB models — what makes the 1TB ST1000NM0008 the right choice over the 2TB version?

Choose the 1TB model when your workload fits within a single terabyte and you want the same 7200 RPM, 128MB cache, CMR technology and 550TB/yr rating at a lower acquisition cost.

The spec lists 7200 RPM and 128MB cache — what sustained throughput can I expect once the drive is installed in a RAID array?

In a multi-drive RAID the Exos 7E2 delivers consistent 24x7 performance thanks to rotational-vibration safeguards and on-the-fly error correction, sustaining workloads up to 550TB per year.
