Enterprise 900 GB SAS Drive

The HGST Ultrastar C10K900 is a new 900 GB 2.5-inch internal hard drive with a 10000 RPM spindle and 64 MB cache. It connects through a SAS 6Gb/s interface and measures 14.8 mm in height. The bare drive is built on a field-proven design intended for enterprise workloads.

Suited For Enterprise Arrays

This drive suits administrators who need high-throughput SAS storage in a 2.5-inch form factor for servers or storage arrays. It is not suited for systems that lack a SAS host bus adapter or backplane. Buyers who need a different capacity or a lower spindle speed should look at other models.

Deciding Specification

The SAS 6Gb/s interface is the single specification that decides compatibility. The drive requires a controller or backplane that supports this exact interface and transfer rate. Without a matching SAS connection the drive cannot be used.

Questions about this item

How do I install the 2.5" 10000 RPM SAS drive in a laptop, and what step is often missed?

Fit the bare drive into the 2.5" bay, connect the SAS data and power cables, then ensure the host controller detects the 6Gb/s link — many forget to enable the SAS port in BIOS.

What maintenance or replacement will the 900GB Ultrastar C10K900 need later?

No scheduled maintenance is required; the sealed 64MB cache mechanism runs until the drive reaches its rated workload limit, at which point the whole unit is replaced.

What limit appears first when the 6Gb/s SAS drive runs sustained workloads?

The 10000 RPM spindle and 28% lower operating power mean the thermal envelope is reached before the 6Gb/s interface saturates.
