WD Ultrastar C10K1800 HUC101830CSS200 - hard drive - 300 GB - SAS 12Gb/s

HGST delivers best-in-class performance and capacity in one small form factor hard drive. The Ultrastar C10K1800 is a 10K RPM enterprise-class HDD that stores lots of data, 50% more capacity than prior generations, plus delivers best-in-class active and idle power efficiency, enabling next generation data centers to keep pace with digital data growth and improve space and power efficiencies. Data center architects can also leverage best-in-class performance on the C10K1800, achieving up to 2.5X better random write performance and 23% faster sequential performance over prior generation 2.5-inch SFF 10K RPM HDDs for demanding 24x7 enterprise workloads.

Amazing performance is achieved through several HGST technology innovations including media cache architecture, 12Gb/s SAS interface and advanced format options. HGST's media cache architecture is a disk-based caching technology, which provides a large non-volatile cache on the media resulting in improved reliability and data integrity during unexpected power loss, as well as a significant improvement in write performance even at high workloads when compared to solutions with limited NAND or flash-based NVC. The C10K1800 is the industry's first 10K RPM drive to leverage 12Gb/s SAS interface, enabling very high transfer rates between host and drive.
