Capacity and interface

This HP 861681-B21 is a 2 TB internal hard drive with a 3.5 inch form factor. It spins at 7200 RPM and connects through a SATA 6.0Gb/s interface. The drive is supplied new in retail or OEM packaging. It is built for desktop and server storage tasks.

Server and desktop storage fit

The drive suits administrators adding bulk capacity to an HPE Apollo 4200 Gen9 server or to a standard desktop chassis. Buyers who need solid-state speed or a 2.5 inch form factor should look at other options. It is not a flash-based device and does not fit slim bays.

7200 RPM spindle speed

The 7200 RPM spindle speed determines the sustained transfer rate and access latency for sequential workloads. This figure is the primary specification to check against your performance requirements. Verify that your system can accommodate a 3.5 inch SATA drive before purchase.

Questions about this item

How much heat or noise does the 7200 RPM drive produce when running continuously?

The 7200 RPM spindle speed and SATA 6.0Gb/s interface are designed for typical server workloads; actual acoustics and temperature depend on the chassis airflow and mounting.

What SATA host connector and power cable does the 3.5" drive need to operate?

The drive uses a standard SATA data port and a SATA power connector; the system must provide both to function.

Will the 2 TB SATA drive work in an older server that only supports SATA 3.0Gb/s?

The SATA 6.0Gb/s interface is backward compatible with SATA 3.0Gb/s controllers, so the drive will operate at the lower link speed.
