Enterprise 15K SAS drive

The HGST Ultrastar C15K600 is a 600GB 2.5-inch hard drive spinning at 15030 RPM with a SAS 12Gb/s interface and 128MB cache. It targets Tier 0 and Tier 1 applications that demand the lowest latency and highest random transaction rates in enterprise servers and storage arrays. Average seek time is 2.9ms and average latency is below 2.0ms.

Compatibility checks

Verify that your system provides a SAS 12Gb/s backplane or controller and a 2.5-inch bay accepting a 14.8mm drive height. The drive uses a 512N sector format and draws power from the SAS connector; no separate power cable is required. Confirm firmware and HBA driver support for 12Gb/s operation before installation.

Bare-drive impact

The unit ships as a bare drive without rails, cables, mounting screws or software utilities. You must supply a compatible drive carrier or caddy for your server chassis and any encryption management tools if you plan to use the available ISE, TCG-SED or FIPS 140-2 certified TCG-SED security models.

Questions about this item

Does the bare drive include mounting hardware or cables, or must they be purchased separately?

The drive ships as a bare unit only; mounting brackets, screws and SAS data/power cables are not included and must be sourced separately.

Should I choose the 512N SE option or another capacity for this 600GB model?

This listing is the single 600GB capacity with 512-byte native sectors; no other capacity or sector-size variant is offered for this part number.

How does the 15030 RPM spindle speed affect real-world latency and seek performance?

The 15030 RPM rotation yields an average latency below 2.0ms and average seek times of 2.9ms read and 3.1ms write, delivering the low-latency response expected in Tier 0/1 enterprise workloads.
