Enterprise Storage Drive

The HGST Ultrastar C10K1800 is a 1.2TB 2.5-inch hard drive built for enterprise storage arrays and high-performance servers. Its 10520 RPM spindle speed and 128MB cache target Tier 1 applications such as databases, OLTP and HPC workloads that demand 24x7 availability. The SAS 12Gb/s interface and 512n Instant Secure Erase suit environments where data security and rapid drive retirement are required.

Thermals and Power

Advanced Power Management optimizes power consumption during normal operation, delivering best-in-class power efficiency for space-constrained racks. The 10520 RPM mechanism is engineered for sustained throughput while keeping thermal output controlled within enterprise chassis airflow designs. A 2M hour MTBF rating reflects the reliability expectations for continuous duty cycles in mission-critical deployments.

Build Integration

The 2.5-inch form factor fits high-density drive bays and hot-swap backplanes using the SAS 12Gb/s connection. 512n sector formatting ensures compatibility with legacy enterprise controllers and operating systems without translation overhead. Instant Secure Erase simplifies decommissioning by removing data instantly, freeing administrators from lengthy overwrite procedures when drives leave the secure environment.

Questions sur cet article

How do I install this 2.5" SAS drive in a server bay and what step is often missed?

Mount the 2.5" drive in a compatible SAS backplane or tray, connect the SAS 12Gb/s data and power cables, then enable the drive in the RAID controller BIOS so the 1.2TB volume appears to the OS.

What maintenance or replacement will this enterprise drive need during its service life?

With a 2M hour MTBF rating and Instant Secure Erase, the drive itself needs no scheduled maintenance; plan replacement only if SMART attributes flag degradation or when capacity must expand beyond 1.2TB.

What limit appears first when this 10520 RPM drive runs sustained workloads?

The 12Gb/s SAS interface and 128MB cache sustain high throughput, so the mechanical 10520 RPM rotational latency becomes the first bottleneck during continuous random I/O.
