The Ultrastar 0F48155 DC HC570 incorporates a range of technologies in a 9-disk platform to create a new class of hard drives.
The 22TB capacity is achieved by combining technologies that enhance space density in conjunction with technologies that improve performance and reduce power consumption.
The Ultrastar DC HC570 22TB data center hard drive with OptiNAND technology is the next leap in data density. This 22TB data center hard drive enables an incredible 22.44 PB of raw storage in a standard rack.
This higher volumetric density allows data centers to maximize their storage, especially in footprint and power-constrained environments.
The Ultrastar DC HC570 combines many industry-first technologies in a 10-disk CMR unit, providing the performance, quality, and reliability that data center customers demand.
Ultrastar hard drives are designed for optimal power in various workloads. The DC HC570 features low-power sequential read/write and mixed random read/write workloads.
The Ultrastar DC HC570 is the 2nd generation platform with OptiNAND technology, which integrates an embedded flash drive (EFD) iNAND® Universal Flash Storage (UFS) with traditional spinning disk media.
Western Digital's leadership in 2.2 TB/disk area density extends to a new 10-disk platform, providing 22TB capacity with CMR recording format.
OptiNAND improves the unit's resilience in the event of an emergency power-off (EPO) by increasing the amount of non-volatile memory (NVM) available to flush critical metadata to iNAND.
The explosive growth of data from AI/ML, 5G networks, IoT, connected vehicles, and more is fueling the development of data centers. The innovation of hard drives is leading to the ability to capture, store, analyze, and protect a large portion of this data. Higher capacity HDDs provide greater data density, enabling the expansion and efficiency of the data center.
Ultrastar HDD hard drives are designed for optimal power in various workloads. The DC HC570 drive features low power consumption for sequential read/write and mixed random read/write workloads.
OptiNAND enhances the unit's durability in the event of an emergency power-off (EPO) by increasing the amount of non-volatile memory (NVM) available for clearing critical metadata in iNAND.
The Ultrastar DC HC570 is the 2nd generation platform with OptiNAND technology, which integrates an embedded iNAND® Universal Flash Storage (UFS) Embedded Flash Drive (EFD) with traditional spinning disk media.
ArmorCache™ is a feature enabled by OptiNAND that combines the performance of Write Cache Enable (WCE) mode and the data protection of Write Cache Disable (WCD) mode, offering the best of both scenarios. When operating in WCE mode, ArmorCache ensures that the DRAM cache will be safely written in the event of an Emergency Power Off (EPO) and no data will be lost. When operating in WCD mode, the drive ensures that all user data in DRAM is safely written in the event of an EPO and the drive will operate with performance equivalent to WCE. The performance and data protection are now identical in both WCE and WCD modes.
The Ultrastar DC HC570 meets the modern reliability demands of data centers with an MTBF2 of 2.5M (projected) and a 5-year limited warranty. It is performance-optimized for large application workloads and is designed to handle workloads of up to 550TB per year. It offers security and encryption options to protect data from unauthorized use, including SED models. Trust Western Digital and the Ultrastar DC HC570 hard drive to provide the highest capacity and greatest value for your data center.
