HGST Ultrastar C15K600 HUC156060CSS204 600GB 15000 RPM SAS 12Gb/s 2.5" internal hard drive

Enterprise Storage Drive

The HGST Ultrastar C15K600 is a 2.5 inch internal hard drive built for enterprise storage systems. It delivers 600GB capacity through a SAS 12Gb/s interface and spins at 15000 RPM with a 128MB cache buffer. The drive uses 512n sector formatting and is supplied as a bare unit. It targets Tier 0 and Tier 1 applications that demand consistent high-speed access.

Suited For High IOPS Workloads

This drive suits database servers, transactional systems and caching layers that benefit from 15000 RPM rotational speed and low latency. The 128MB cache and SAS 12Gb/s bandwidth support sustained random read and write performance. Buyers needing larger capacity per spindle or lower power draw should look at alternatives. The 2.5 inch form factor fits dense server chassis but requires a compatible SAS backplane or controller.

600GB Capacity With 128MB Cache

The 600GB capacity handles active datasets, log volumes and hot-tier storage where speed outweighs raw space. The 128MB cache absorbs burst traffic and reduces mechanical seeks during mixed workloads. At 15000 RPM the drive reaches its performance ceiling on sequential throughput limited by the physical media. Workloads exceeding 600GB of hot data will require multiple drives or a different storage tier.
