Capacity and interface

The HGST Ultrastar A7K2000 0F10452 is a 2 TB 3.5 inch desktop internal hard drive with a SATA 3.0Gb/s interface. It spins at 7200 RPM and includes 32 MB of cache for responsive data access. The drive is built for 24x7 enterprise-class duty cycles and targets a 1.2 million hour MTBF.

Upgrade from prior generation

This model provides twice the data storage capacity of the prior Ultrastar A7K1000 drive while using fewer watts. The jump is worth it when you need more space in the same footprint without increasing power or cooling demands. Enhanced Rotational Vibration Safeguard helps maintain robust performance in multi-drive environments.

Headroom and limits

The drive comfortably handles high-capacity bulk storage such as large media libraries, backups or archival workloads in desktop or server chassis. In a dense deployment, ten 4U 60-bay enclosures can reach 1.2 petabytes in a standard 19 inch rack. It runs out when workloads demand solid-state latency or throughput beyond mechanical rotational speeds.

Questions about this item

Does the 3.5" drive need any adapter to mount in a standard desktop bay?

The drive uses the standard 3.5" form factor so it fits directly into any desktop bay with four side or bottom screws. No adapter bracket is required.

What is the correct way to connect the SATA 3.0Gb/s interface and the step installers often miss?

Attach both the SATA data cable and the SATA power connector from the PSU. The step often missed is seating the power plug fully until it clicks; a loose connection prevents spin-up.

When should the 32MB cache drive be replaced under continuous 24x7 operation?

The drive is rated for a 1.2 million hour MTBF under 24x7 duty. Plan replacement once SMART reallocated sectors appear or after five years of non-stop service.
