Enterprise 900 GB SAS drive
The HGST Ultrastar C10K1800 is a 2.5-inch enterprise hard drive built for servers and storage arrays that need fast, reliable access to large datasets. It spins at 10520 RPM with a 128 MB cache and connects through a 12Gb/s SAS interface.
Upgrade from prior 10K SFF drives
This model delivers 2.5X faster random write performance and 23% faster sequential performance over the previous generation of 2.5-inch 10K RPM drives. The jump is worth it when workloads demand lower latency and higher throughput for mission-critical applications.
Suits high-density enterprise storage
It fits 15 mm drive bays in compatible servers and arrays where 900 GB capacity and 2M hours MTBF are required. Builders needing a different capacity, a 512n sector format, or a non-SAS interface should look at other models.

In stockQuestions about this item
Will the 15mm height fit my 2.5" SAS bay?
The drive measures 15mm high, 70.10mm wide and 100.45mm long, matching the standard 2.5-inch SFF form factor used in enterprise servers and storage arrays.
What is the correct SAS cabling step that is often missed?
Connect the 12Gb/s SAS data and power cables to the backplane or HBA, then verify the controller detects the 900GB LUN before initializing the volume.
When should I plan to replace this enterprise drive?
The 2M-hour MTBF rating and non-volatile media cache are designed for continuous operation; monitor SMART reallocated-sector counts and replace if they rise sharply.
