Ultrastar 300 GB 10K RPM Enterprise Drive

The HGST Ultrastar 0B24153 is a 2.5-inch laptop internal hard drive built for enterprise workloads. Its 10,000 RPM spindle speed and 64 MB cache target servers and workstations that need low-latency access to hot data. The bare-drive packaging suits system integrators and upgrade scenarios where no retail accessories are required.

SATA 6.0 Gb/s Interface Decides Fit

This drive connects through a SATA 6.0 Gb/s interface, so the host must provide a compatible SATA port and controller. The 300 GB capacity is fixed; buyers who want more storage must choose a different model. The 3.7 ms average seek time and 3 ms average latency reflect the high rotational speed but do not change the interface requirement.

Standard 2.5-Inch Mount With Enterprise Features

Installation follows the usual 2.5-inch SATA drive procedure: secure the drive in a caddy or bay, attach the data and power cables, and initialise the volume in the operating system. The bare drive ships without screws, brackets or cables, so installers must supply them. Rotational Vibration Safeguard and workload detector technology help maintain performance in multi-drive arrays, yet vibration isolation in the chassis remains the installer's responsibility.

Questions about this item

How does the 10000 RPM speed affect everyday performance in a laptop?

The 10000 RPM spindle reduces average latency to 3 ms and average seek time to 3.7 ms, so the drive locates and begins reading data faster than slower-spinning drives, cutting load times for applications and large files.

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

The SATA 6.0Gb/s link caps maximum sustained throughput at the interface level, so the drive cannot exceed that bandwidth even though its 64 MB cache and 10000 RPM mechanics can feed data more quickly.

Will this 2.5-inch drive fit a standard laptop bay?

The 2.5-inch form factor matches the common laptop drive bay, but the bare-drive packaging means no mounting bracket or screws are included, so you must reuse hardware from the old drive or supply your own.
