Product identity

The HP 872475-B21 is a 300GB 2.5-inch enterprise hard drive spinning at 10000 RPM with a SAS interface. It is built for servers and storage arrays that need fast access to hot data in a small form factor.

Capacity and headroom

The 300GB capacity suits workloads such as transactional databases, virtualization hosts and high-performance caching tiers. It runs out when datasets grow beyond a few hundred gigabytes or when capacity-per-drive matters more than IOPS.

SAS interface limits

The drive uses a 12G SAS link that tops out at 12 Gbit/s per lane, so sustained throughput cannot exceed that ceiling. Backplanes or controllers limited to 6G will halve the available bandwidth, and the mechanical 10K spindle keeps random latency above solid-state levels.

Questions about this item

Will the 872475-B21 300GB SAS drive work in my older server that only supports 6Gb/s SAS backplanes?

The drive uses a 12G SAS interface which is backward compatible with 6G and 3G SAS controllers, so it will operate at the lower speed supported by your backplane.

How can I confirm the 10000 RPM enterprise drive is healthy and recognised by the controller after installation?

The HPE Smart Carrier shows a solid green LED when the drive is online and healthy; the system BIOS or RAID utility will also list the 300GB capacity and 12G SAS link speed.

Does the 872475-B21 ship with a mounting tray, screws or cables, or must I source them separately?

The drive is supplied in the HPE Smart Carrier (2.5" SFF tray) ready for hot-plug bays; no data or power cables are included as the carrier connects directly to the backplane.
