  • 10 000 RPM spindle delivers fast data access
  • SAS 6 Gb/s interface enables high-throughput transfers
  • 5 inch form factor fits dense server bays

900 GB SAS 10K enterprise drive

The HGST Ultrastar C10K900 is a 2.5-inch hard drive built for servers and storage arrays that require a SAS 6 Gb/s connection. It spins at 10K RPM and provides 900 GB of capacity for transaction-heavy workloads.

SAS 6 Gb/s interface limit

The 6 Gb/s SAS link caps sustained throughput below the drive’s inner-track potential, so sequential reads can saturate the bus. Systems limited to 3 Gb/s backplanes will halve that ceiling, and the mechanical latency remains fixed regardless of controller speed.

Highlights

  • 900 GB capacity stores large datasets
  • 10 000 RPM spindle delivers fast data access
  • SAS 6 Gb/s interface enables high-throughput transfers
  • 5 inch form factor fits dense server bays

Questions about this item

Should I pick the 900 GB SAS 6 Gb/s 10 K RPM 2.5-inch model or a different capacity?

The 900 GB capacity with 10 K RPM and SAS 6 Gb/s is the only version listed for the HUC109090CSS600, so there is no alternative capacity to compare.

What does the 10 K RPM figure mean once the drive is installed in a server?

A 10 K RPM spindle speed on a SAS 6 Gb/s interface delivers high random I/O performance for transaction-heavy workloads in a 2.5-inch form factor.
