Silver 2.5 inch SAS hard drive with green circuit board

DELL

DELL 9RZ264-150 500GB 7.2K SAS 6G 2.5in internal hard drive

SKU CH-5EJ2-JKGNV

A 2.5in SAS hard drive holding 500GB at 7200RPM with 64MB cache for compatible PowerEdge servers

  • 500 GB storage for enterprise workloads
  • 7200 RPM spindle speed for responsive data access
  • SAS 6 Gb/s interface for reliable server connectivity
  • 64 MB cache to smooth burst I/O
  • Compatible with Dell PowerEdge M, R and T series servers

500 GB SAS 6 Gb/s drive

This 500 GB 2.5 in hard drive spins at 7200 RPM and uses a SAS 6 Gb/s interface. It is built for Dell PowerEdge servers that accept small-form-factor SAS disks. The 64 MB buffer helps smooth sustained reads and writes in multi-drive arrays. Buyers needing higher capacity or a different interface should look elsewhere.

Compatibility checklist

Verify that your server model appears in the supported list such as R610, R710, T410 or M610. Confirm the backplane provides a 2.5 in SAS bay and that the controller supports 6 Gb/s speeds. Check whether a drive carrier or caddy is required for your specific chassis. Ensure firmware revision matches the system requirements before installation.

Build and daily use

The drive weighs 1.0 pound and follows the standard 2.5 in SFF form factor. A single SAS connector handles both data and power, simplifying cable routing in dense enclosures. Hot-plug capability depends on the server backplane design. The 7200 RPM spindle delivers consistent throughput for typical server workloads.

Questions about this item

Does the 9RZ264-150 ship with a mounting bracket or caddy for the 2.5in bay, or must I order that separately?

The drive is supplied as the bare 2.5in SAS unit only; any Dell hot-plug caddy or tray for your specific PowerEdge model must be purchased separately.

I see the same part listed with different model numbers — ST9500620SS and 9RZ264-150 — which one should I select?

Both numbers refer to the identical 500GB 7200RPM SAS drive; 9RZ264-150 is Dell's order code while ST9500620SS is the manufacturer's model, so either reference points to the same hardware.

What does the 7200RPM spindle speed mean for everyday server workloads on a 6Gb/s SAS link?

The 7200RPM rotation gives consistent low-latency access for random I/O, while the 6Gb/s SAS interface provides ample headroom for the drive's sustained throughput in RAID arrays or single-drive configurations.
