2 TB Exos drive for desktop storage

The Seagate Exos ST2000NM000A is a 2 TB internal hard drive built for desktop systems that use a 3.5 inch SATA bay. It spins at 7200 RPM and provides a 256 MB buffer to keep sustained transfers steady. The drive uses the 512n sector format and connects through a SATA 6.0 Gb/s interface. It is supplied new in either retail or OEM packaging.

Suits capacity-focused builds, not speed-first ones

This drive fits builders who need affordable bulk storage for backups, media libraries or archival workloads where sequential throughput matters more than random access latency. It is not intended for users who want the low latency of solid-state storage or who need higher capacities than 2 TB in a single bay. Systems limited to slower SATA revisions will still work but cannot reach the drive’s maximum transfer rate.

512n sector format decides compatibility

The 512 native sector size ensures broad compatibility with older operating systems, RAID controllers and backup software that do not support advanced format drives. If your platform requires 4Kn sectors, this model will not match that requirement.

Questions about this item

How loud and hot does the 7200 RPM Exos drive run during continuous operation?

The 3.5" drive spins at 7200 RPM with a 256 MB buffer; typical acoustics for this class are audible but moderate, and the 1.37 lb chassis dissipates heat through the metal case.

What existing cables and bay does the SATA 6.0Gb/s 3.5" drive require?

You need a standard SATA data cable, a SATA power connector from your PSU, and an available 3.5" drive bay or 2.5"/3.5" adapter bracket in the chassis.

Will the 512n sector format work with my older motherboard that only supports 512-byte sectors?

Yes, the 512n native sector size matches legacy 512-byte sector expectations, so the drive is recognised without translation layers on older SATA controllers.
