4 TB SATA drive for HPE Apollo 4200 Gen9

This 3.5 inch internal hard drive delivers four terabytes of storage on a SATA interface. It spins at 7200 rpm and is built for server workloads in the Apollo 4200 Gen9 platform. The drive is supplied new in either retail or OEM packaging.

SATA 600 interface practical limits

The SATA 600 standard caps the theoretical transfer rate at six gigabits per second. Real-world throughput is lower due to protocol overhead and the mechanical limits of a 7200 rpm platter. The drive cannot exceed the bandwidth of the SATA bus regardless of system capabilities.

Installation in Apollo 4200 Gen9 bays

The drive fits the 3.5 inch hot-swap bays of the HPE Apollo 4200 Gen9 without adapters. Common issues include inserting the carrier upside down or not seating the connector fully, which prevents the server from detecting the drive.

Questions about this item

Is the 4 TB capacity the only option for the 861683-B21 model?

The 861683-B21 is sold as a 4 TB drive; other capacities carry different part numbers.

What does the 7200 rpm spindle speed mean for daily server workloads?

The 7200 rpm rotation delivers consistent throughput for bulk storage and sequential reads in the Apollo 4200 Gen9.

How does the SATA/600 interface affect real-world transfer rates?

The SATA/600 link caps the drive at 600 MB/s, so sustained speeds will not exceed that ceiling.
