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.

Questions about this item
Does my server backplane need a SAS 12Gb/s port to use this 600 GB 15 000 RPM drive?
Yes, the drive uses a SAS 12Gb/s interface, so the host or backplane must provide a compatible SAS port for it to operate.
Will this 2.5 inch SAS drive work in the same enclosure as my older 6 Gb/s SAS disks?
The drive supports SAS 12Gb/s and will negotiate down to 6 Gb/s when installed alongside older SAS devices in the same enclosure.
How can I verify the 128 MB cache and 15 000 RPM speed are active after installation?
Check the drive identification page in your RAID controller BIOS or OS utility; it will report 15 000 RPM rotational speed and a 128 MB cache buffer.
