Enterprise SAS Hard Drive

The HGST Ultrastar C10K1800 is a 600GB 2.5-inch enterprise hard drive spinning at 10520 RPM with a SAS 12Gb/s interface and 128MB cache. It is built for high-performance servers and storage arrays handling hot and warm data in data centre environments. The bare drive measures 15mm in height, 70.1mm wide and 100.45mm long.

Suited For Enterprise Workloads

This drive targets tier 1 enterprise servers, HPC clusters, databases and OLTP applications that demand high reliability and low latency. Buyers who need a consumer laptop upgrade or a drive for a standard desktop chassis without a SAS controller should look elsewhere. Systems requiring a different physical height or interface protocol are not compatible with this 15mm enterprise form factor.

SAS 12Gb/s Interface Decides Fit

The single specification that determines compatibility is the SAS 12Gb/s interface, which requires a matching SAS backplane or host bus adapter. Without SAS infrastructure, the drive cannot be used. The 10520 RPM speed and 128MB cache support the performance profile, but the interface is the hard requirement for installation.

Questions about this item

How do I install the 2.5" 15mm SAS 12Gb/s drive in a server bay, and what step is often missed?

Mount the 70.1mm × 100.45mm bare drive in a 15mm 2.5" bay, connect the SAS 12Gb/s cable and power, then configure the controller for 512n or 4KN sector size — skipping the sector-size match causes the drive to stay invisible to the OS.

What maintenance or replacement will the 600GB 10520 RPM Ultrastar C10K1800 need during its service life?

The 2M-hour MTBF rating means the drive itself is not user-serviceable; plan to replace the entire unit after the rated period or if SMART attributes show reallocated-sector growth beyond the 128MB cache buffer's ability to mask errors.

What limit appears first when the 12Gb/s SAS drive runs sustained enterprise workloads?

The 10520 RPM spindle caps random I/O at the 3.3-3.5ms seek and 2.85ms latency figures, so the mechanical response time becomes the bottleneck before the 12Gb/s interface or 128MB cache saturates.
