Enterprise Laptop Drive 900GB

The HGST Ultrastar C10K1800 HUC101890CSS200 is a new 900GB 2.5 inch enterprise hard drive spinning at 10520 RPM with a 128MB cache. It connects via SAS 12Gb/s and fits a 15mm high bay. The bare drive delivers 1.8TB class capacity density in a 10K RPM design.

Suits High IOPS Workloads

This drive suits servers and storage arrays that need low average latency of 2.85ms and fast seek times of 3.3 to 3.5ms for random access. Buyers who need a larger single drive capacity than 900GB or a different physical interface should look elsewhere.

SAS 12Gb/s Interface Decides Fit

The single specification that decides compatibility is the SAS 12Gb/s interface, which requires a matching controller or backplane. Without SAS 12Gb/s support the drive cannot be used, regardless of its 2.5 inch form factor or 15mm height.

Questions sur cet article

My server backplane only accepts 15mm 2.5" drives — will this 15mm SAS unit seat correctly?

The drive is built to the 15mm maximum height for 2.5" enterprise bays and uses the standard SAS connector, so it seats directly in any backplane that accepts 15mm SAS drives.

Can I mix this 10520 RPM SAS drive with older 10K SAS disks on the same controller?

Yes — the 12Gb/s SAS interface negotiates down to 6Gb/s or 3Gb/s, allowing the 900GB 10520 RPM drive to share a controller with earlier 10K SAS models.

How do I confirm the 128MB cache and 12Gb/s link are active after installation?

Check the controller BIOS or OS utility for a reported 12Gb/s negotiated speed and 128MB cache size; the drive also reports 10520 RPM and 2.85ms average latency when queried via SMART.
