Ultrastar DC HC550 integrates a suite of technologies on a 9-disk platform to create a new class of HDDs. 16TB capacity is achieved by combining technologies that improve areal density working together with technologies that improve performance and reduce power consumption. The first HDD in the industry to harness Energy- Assisted Magnetic Recording (EAMR) technology improves writability and therefore increases areal density. The industry’s first Triple Stage Actuator (TSA) enhances head-positioning accuracy, delivering better performance and increased areal density. HelioSeal technology is the foundation for Western Digital’s high capacity HDDs and this is the 6th generation of HelioSeal product. Western Digital has shipped >65 million HelioSeal products to date. With its massive capacity and 2.5M MTBF (projected) reliability rating, the Ultrastar DC HC550 is ideal for object storage implementations. Object storage systems with erasure coding provide better data durability compared to RAID systems, given their tolerance for simultaneous error conditions. The DC HC550 offers security and encryption options to help protect data from unauthorized use, including SED models in SAS. Trust Western Digital and the Ultrastar DC HC550 hard drive to deliver highest capacity, lower TCO and more value to your data center. More accurate head positioning, especially in multi-drive environments, for better performance and data integrity. Maintains drive performance in high rotational vibration environments and multi-drive systems Better random write performance. Provides compatibility with high-performance data centers. Improves response time and data management. Available in 16GB capacity.
