24TB to Fuel Data Center Expansion

The relentless growth of data means organizations must find ways to efficiently store more data. That's where higher areal density comes into play, with its ability to boost capacities while not increasing the storage footprint. The Ultrastar DC HC580 with OptiNAND technology is the next step in data density, allowing data centers to maximize their storage, especially in footprint- and power-constrained environments.

This 24TB drive combines several innovative technologies, including energy-assist magnetic recording (EAMR), HelioSeal, triple-stage actuator (TSA) that improves TPI capability with great control over the actuator arm, improved OptiNAND Technology and ArmorCache. This innovation is incorporated into a 10-disk CMR drive, delivering the performance, quality, and reliability that data center customers require.

Low Power for Lower Operating Costs

Innovative technologies, such as OptiNAND and energy-assisted magnetic recording (EAMR), triple-stage actuator (TSA), and HelioSeal enable high capacity with low power.

OptiNAND Technology Benefits

The Ultrastar DC HC850 is a platform with OptiNAND technology, which integrates an iNAND Universal Flash Storage (UFS) Embedded Flash Drive (EFD), with traditional spinning disk media. Western Digital's 2.4TB/disk CMR areal density is used with its 10-disk platform, delivering a 24TB capacity with a CMR recording format. More disks and high areal density work together to maximize data storage efficiency.

OptiNAND improves drive resiliency in the even of an emergency power off (EPO) by increasing the amount of non-volatile (NVM) available to flush critical metadata to the iNAND.

ArmorCache enabled by OptiNAND technology ensures that all the data in the DRAM cache is safely written to the onboard NVM device, should a sudden power loss even occur. Power to a host system may be lost without warning; operating HDD's with write cache disable (WCD) reduced the risk of data loss. With ArmorCache technology, host flush cache commands are no longer necessary to protect data, allowing for maximum performance in either WCD or write cache enabled (WCE) mode. This feature provides enterprise power loss protection of data in WCE while increasing performance in WCD mode.

Trusted Reliability and Quality for Data at Scale

The Ultrastar DC HC580 meets modern data center reliability requirements with 2.5M MTBF (projected) and a limited 5-year warranty. It is performance-optimized for heavy application workloads and is designed to handle workloads up to 550TB per year.
