Seagate Exos 7E8 ST2000NM0045 2TB 7.2K SAS 12Gb/s 3.5" internal hard drive

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.
