Dell 73GB 15000RPM SAS drive

This 3.5-inch internal hard drive delivers 73GB of storage on a 3Gb/s SAS interface. Its 15000RPM spindle speed and 16MB cache target enterprise servers and high-performance workstations that need fast random access for transactional workloads. The drive is supplied new and suits arrays where low latency matters more than raw capacity.

Capacity and headroom

Seventy-three gigabytes provides enough space for operating systems, databases or email stores that benefit from rapid seek times. The 15000RPM rotation keeps sustained throughput high for sequential tasks, yet the modest capacity fills quickly with media libraries or large virtual-machine images. Heavy archival workloads will outgrow the available space long before the interface saturates.

Bundled impact

No accessories, mounting hardware or management software are included with the bare drive. Integration therefore depends entirely on the host chassis backplane and controller firmware. Buyers who need hot-swap trays, cables or RAID configuration utilities must source those separately from their server vendor.

Questions about this item

Will the 3Gb/s SAS interface on the ST373455SS work with an older SAS controller?

The drive uses a 3Gb/s SAS interface. It will negotiate down to the speed supported by the controller, but specific backward-compatibility depends on the controller model.

How can I verify the ST373455SS is operating correctly after installation?

Check that the BIOS or RAID controller detects a 73GB SAS drive at 15000RPM. Run the manufacturer's diagnostic tool to confirm SMART data shows no errors and the 16MB cache is active.

What comes in the box with the ST373455SS and what must I buy separately?

The drive itself is supplied. You will need a 3.5" SAS backplane or cable, a compatible SAS controller or HBA, and mounting screws for your chassis.
