Capacity and Interface

This HPE 870755-B21 internal hard drive provides 300 GB of storage on a 3.5 inch form factor. It connects through a SAS interface operating at 12Gb/s SAS speed. The spindle rotates at 15000 rpm for rapid data access. The unit is designated for server environments.

Server workloads and compatibility

The drive suits administrators who need high-speed rotational storage for transaction-heavy server workloads. It is not intended for desktop PCs or external enclosures lacking a 12Gb/s SAS host bus adapter. Buyers requiring larger capacities or solid-state latency should evaluate alternative media. Systems without native SAS backplane support cannot use this device.

Deciding specification

The 15000 rpm spindle speed is the defining characteristic that determines suitability for latency-sensitive server applications. This rotational velocity directly governs random I/O response times. Verify that the target server chassis and controller both support 3.5 inch 12Gb/s SAS drives before purchase. The 300 GB capacity follows from the high-speed mechanical design.

Questions about this item

How much heat and noise does the 15000 rpm SAS drive generate during continuous server operation?

The 15000 rpm spindle speed means higher sustained heat output and audible mechanical noise compared to slower drives; ensure the server chassis provides adequate airflow for 3.5" bays.

What host interface and connector must the server already provide for this 12Gb/s SAS drive?

The server backplane or controller must support 12Gb/s SAS with a standard 3.5" SAS connector; no additional adapters are included.

Will this 300 GB 12Gb/s SAS drive work in a server that only has 6Gb/s SAS backplanes?

Yes, the drive is backward compatible with 6Gb/s SAS infrastructure, though it will operate at the lower 6Gb/s link speed.
