Enterprise SAS drive for 2.5-inch bays

The HGST Ultrastar C10K1800 HUC101812CSS200 is a new 1.2TB hard drive with a 12Gb/s SAS interface. It spins at 10520 RPM and includes a 128MB cache for high-throughput workloads. The 15mm height fits standard enterprise 2.5-inch drive bays.

Suits servers needing 12Gb/s SAS and 10K speed

This drive serves administrators who require the 12Gb/s SAS protocol and 10520 RPM performance in a 2.5-inch form factor. Buyers whose systems only accept a 7mm z-height or a different interface cannot use this unit. The bare-drive packaging also means no mounting tray is included.

12Gb/s SAS interface decides compatibility

The single specification that determines fit is the 12Gb/s SAS interface; the host backplane or controller must support this exact protocol. A 12Gb/s SAS connection is required to realise the rated transfer rate and to communicate with the drive at all.

Questions about this item

Will the 15mm height fit my laptop's 2.5" drive bay?

The drive measures 15mm tall, 70.1mm wide and 100.45mm long; check your laptop's bay depth and height clearance before buying.

How do I connect the SAS 12Gb/s interface, and what step is often missed?

Attach the SAS data and power cables to the controller, then ensure the backplane or HBA is set to 12Gb/s mode — many forget to enable the higher link speed in firmware.

When should I expect to replace the 1.2TB 10520 RPM drive?

Enterprise 10K drives are rated for continuous operation; monitor SMART reallocated-sector counts and plan replacement once the attribute approaches threshold.
