HGST Ultrastar C15K600 HUC156060CSS200 600GB 15000RPM 12Gbps 2.5in SAS internal hard drive

SKU CH-PY1C-8P6M9

A 600 GB, 15,000 RPM SAS drive with a 128 MB cache for high-performance servers and transaction-heavy databases

  • 15,000 RPM spindle speed delivers rapid data access for transaction-heavy workloads
  • 12 Gbps SAS interface moves large datasets quickly between server and storage
  • 128 MB cache buffers bursts to sustain throughput during peak I/O
  • 600 GB capacity fits dense 2.5-inch bays in blade and rack systems
  • Rotational Vibration Safeguard maintains performance in multi-drive enclosures

600 GB 15 000 RPM SAS drive

The HGST Ultrastar C15K600 is a 2.5 inch internal hard drive built for high-performance computing and mission-critical workloads that demand 24x7 availability. It spins at 15 000 RPM and connects through a 12 Gbps SAS interface with a 128 MB buffer. Media Caching Technology, Workload Detector Technology and Rotational Vibration Safeguard are integrated to sustain reliability in dense server deployments.

Enterprise servers needing sustained throughput

This drive suits blade, pedestal and rack-mounted servers handling databases and intense online transaction processing where data security and compliance are priorities. It is not for systems that lack a 12 Gbps SAS backplane or that require larger capacities for bulk storage. Desktop workstations and consumer NAS units without SAS controllers cannot use it.

12 Gbps SAS interface decides fit

The single specification that determines compatibility is the 12 Gbps SAS connection; the host must provide a matching SAS port and backplane support. Without that interface the drive cannot be installed or operated. Buyers should verify their server or storage array accepts 2.5 inch SAS drives at 12 Gbps before purchasing.

Questions about this item

Will the 128MB cache or 15000RPM spindle require periodic replacement?

The 128MB cache and 15000RPM spindle are sealed inside the drive; no user-serviceable parts exist, so no scheduled replacement is needed.

Which limit appears first during sustained 12Gbps SAS writes — thermal throttle or interface saturation?

The 12Gbps SAS interface typically saturates before the 15000RPM mechanism reaches its thermal ceiling under continuous write workloads.

How much heat and noise does the 15000RPM 2.5in SAS drive produce in 24x7 operation?

The 15000RPM spindle and 12Gbps SAS controller generate noticeable heat and audible seek noise; adequate airflow in the server chassis is required for 24x7 use.
