Enterprise 2.5" SAS Drive

The HGST Ultrastar 0B23909 is a 600GB 10000 RPM laptop internal hard drive with a SAS 6Gb/s interface and 64MB cache. Designed for enterprise environments, it delivers low latency and high reliability in a 2.5 inch bare drive form factor. Advanced power management reduces energy requirements while maintaining performance.

Suited For And Not For

This drive suits server and storage array builders who need dual-port SAS connectivity, rotational vibration safeguards, and consistent 10000 RPM throughput for RAID deployments. It is not for users whose laptop or enclosure only accepts a single-port consumer interface, nor for workloads demanding capacities above 600GB or silent solid-state operation.

Deciding Specification

The SAS 6Gb/s dual-port interface is the single specification that determines compatibility; the host system must provide a matching SAS backplane or controller to utilise the drive. Without that enterprise connection the drive cannot function, regardless of its 3.7ms seek time or 64MB buffer.

Highlights

  • 10000 RPM delivers 3.7ms seek time for rapid data access
  • 64MB cache buffer manages data efficiently during heavy workloads
  • SAS 6Gb/s dual-port interface provides fast, reliable connectivity
  • 600GB capacity fits in a 2.5 inch form factor for space savings
  • Advanced power management reduces energy use while maintaining enterprise performance

Questions about this item

Does the HGST 0B23909 include cables, brackets or mounting screws in the bare-drive package?

The 0B23909 ships as a bare 2.5" drive only; no data cables, mounting brackets or screws are included and must be sourced separately.

Which capacity of the Ultrastar 0B23909 series should I choose for a 10 000 RPM SAS laptop drive?

This model is offered in a single 600 GB capacity, so the choice is fixed at 600 GB for the 10 000 RPM SAS 6 Gb/s specification.

What does the 3.7 ms average seek time mean for real-world access speed on this 10 000 RPM drive?

A 3.7 ms average seek time combined with 3 ms average latency gives low-latency random access, suited to transactional workloads on the 600 GB SAS 6 Gb/s platform.
