Enterprise storage drive

The HGST Ultrastar 0B25095 is a 450GB 2.5-inch laptop internal hard drive spinning at 10000 RPM with a SAS 6Gb/s interface. It delivers enterprise-class performance in a compact form factor with 64MB cache and advanced power management for lower power requirements. The bare drive includes Rotational Vibration Safeguard and workload detector technology for multi-drive environments.

Transactional workloads and RAID arrays

This drive suits administrators deploying high-IOPS storage for databases, virtualisation hosts or transactional applications where low latency matters. The dual-port SAS interface provides path redundancy for enhanced reliability in enterprise arrays. Buyers needing larger capacity for archival storage or sequential throughput should consider higher-capacity alternatives.

10000 RPM spindle speed

The 10000 RPM rotation rate determines the drive's average seek time of 3.7ms and average latency of 3ms, which directly govern random I/O performance. This specification decides whether the drive meets the response-time requirements of your workload. If your application prioritises capacity over latency, a different spindle speed may be more appropriate.

Questions sur cet article

What limits the HGST Ultrastar 0B25095 during sustained 10000 RPM operation?

The 3.7 ms average seek time and 3 ms average latency set the mechanical response floor for continuous workloads.

How much heat and noise does the 2.5 inch SAS drive produce when running all day?

Advanced power management lowers power draw, while Rotational Vibration Safeguard keeps acoustics stable in multi-drive systems.

Which controller or backplane must I already have for this 450GB SAS drive to work?

A SAS 6Gb/s dual-port host bus adapter or RAID controller with a 2.5 inch drive bay is required.
