HPE J9F50A 1 TB 2.5" SAS 12Gb/s 7200 rpm internal laptop hard drive

1 TB SAS drive for HP MSA 1040 arrays

This 2.5-inch enterprise hard drive delivers 1 TB of capacity on a 12Gb/s SAS interface. It is built for the HP MSA 1040 Storage Array and operates at 7200 rpm. The drive suits storage-system deployments that require SAS connectivity in a small form factor.

Sustained throughput on 12Gb/s SAS

A 7200 rpm spindle provides consistent rotational latency for mixed read-write workloads. The SAS interface maintains link speed during extended transfers without dropping to a lower rate. Mechanical latency remains stable across the full capacity because the drive does not rely on caching algorithms that degrade when full.

2.5-inch form factor limits

The 2.5-inch enclosure fits dense array bays but cannot accept a 3.5-inch chassis without an adapter. SAS cabling and backplane topology dictate the maximum device count per controller. The 12Gb/s standard sets the electrical ceiling, so the drive cannot exceed that signal rate even if the controller supports a newer generation.
