2 TB SAS drive for enterprise storage

The Seagate Exos 7E8 ST2000NM0045 is a 3.5-inch enterprise hard drive with a 2 TB capacity and a SAS 12Gb/s interface. It spins at 7200 RPM and uses conventional magnetic recording technology. The drive is engineered for 24x7 workloads of 550 TB per year and targets hyperscale applications, cloud data centres and massive scale-out environments.

Thermals noise and power in normal use

The drive operates within standard enterprise temperature ranges and its rotational vibration design helps maintain consistent performance in dense multi-drive systems. Advanced write caching enables up to 100 percent improvement in random writes over the previous generation. Dual processors and ramp load technology contribute to robust operation during continuous duty cycles.

Build fit SAS interface and 3.5 inch form

The bare drive uses an industry-standard 3.5-inch form factor measuring 147.00 mm long, 101.85 mm wide and 26.10 mm high. It requires a SAS 12Gb/s backplane or controller and a 3.5-inch drive bay with appropriate power connectors. The 512n sector format and SATA 6Gb/s compatibility simplify integration into replicated and RAID multi-drive storage servers.

이 상품에 대한 질문

How do I install this 3.5-inch SAS drive and what step is often missed?

Mount the drive in a 3.5-inch bay using the 101.85mm width and 147.00mm length, connect a SAS 12Gb/s cable and a SAS power connector, then ensure the controller initialises the 512n sector format before creating volumes.

What maintenance or replacement will this 2TB enterprise drive need later?

The drive is engineered for 24x7 workloads of 550TB per year; plan replacement when SMART attributes indicate reallocated sectors or when cumulative written data approaches the rated annual limit.

What limit appears first during sustained writes on this 7200 RPM SAS drive?

The 12Gb/s SAS interface caps sustained throughput at 12Gb/s, and the 128MB cache fills quickly, so the 7200 RPM mechanical latency of 4.16ms becomes the bottleneck under continuous random writes.
