Capacity and Interface

The HPE 857648-B21 is a 10TB internal hard drive built for desktop and server storage arrays. Its 3.5-inch form factor and 7200 RPM spindle speed suit bulk data workloads such as backups, archives and media libraries. The drive is hot-pluggable, allowing insertion or removal without powering down the host system.

SATA 6.0Gb/s Interface

The single specification that determines compatibility is the SATA 6.0Gb/s interface, also referenced as SATA/600. The host must provide a matching SATA port and support 10TB volumes. No other interface or protocol is present on this model.

Build Integration

The unit measures 1.1 inches high, 4.2 inches wide and 6.7 inches deep, fitting standard 3.5-inch drive bays. Hot-plug capability requires a backplane or cage that supports blind-mate SATA connectors. The drive draws power from the standard SATA power connector and frees up PCIe slots for other expansion cards.

Questions about this item

What does the 7200 RPM spindle speed mean for real-world throughput?

The 7200 RPM spindle delivers faster sequential read and write rates than slower drives, improving file transfers and application load times on the SATA 6.0Gb/s interface.

What does the SATA 6.0Gb/s interface cap in practice?

The SATA 6.0Gb/s interface limits maximum transfer bandwidth to 6 Gb/s, so sustained speeds top out around the drive's native capability rather than the bus ceiling.

Will the 3.5-inch form factor and 1.1-inch height fit my server bay?

The drive measures 3.5 inches wide, 4.2 inches across, 6.7 inches deep and 1.1 inches high, matching standard 3.5-inch hot-plug server trays.
