1.20 TB SAS 10000 RPM enterprise drive

The HGST Ultrastar C10K1800 HUC101812CS4204 is a 1.20 TB 2.5-inch internal hard drive spinning at 10000 RPM with a 128MB buffer. It uses a 12Gb/s SAS interface and is built for mission-critical applications where proven reliability and consistent performance matter.

Mission-critical arrays suit it.

The drive targets multi-drive environments such as enterprise storage arrays and servers where rotational vibration safeguards maintain throughput. It is not suited for standard laptop bays that lack a SAS controller or backplane, nor for users who need the lowest power draw or silent operation.

12Gb/s SAS interface decides compatibility

The single specification that determines fit is the 12Gb/s SAS interface; the system must provide a matching SAS host bus adapter or backplane for the drive to function. Without that controller the drive cannot communicate, regardless of its 10000 RPM speed or 1.20 TB capacity.

Perguntas sobre este artigo

Does the HGST HUC101812CS4204 ship with a SAS cable, caddy or mounting bracket, or must I source them separately?

The drive is supplied as the bare 2.5" mechanism only; cables, brackets and any laptop caddy are not included and must be obtained separately.

The Ultrastar C10K1800 line includes several capacities — why choose the 1.20 TB model over the others?

The 1.20 TB capacity balances high IOPS from 10000 RPM with a lower cost per drive, making it a good fit for arrays that need many spindles rather than maximum space per bay.

What does the 12Gb/s SAS interface actually deliver once the drive is installed in a server backplane?

The 12Gb/s SAS link supports the full 10000 RPM throughput and 128MB cache burst speeds, while dual-port SAS enables multipath redundancy in multi-drive enclosures.
