Ultrastar® DC HC580 Data Center HDD

24TB / 22TB to Fuel Data Center Expansion

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 24TB / 22TB1 HDD with OptiNANDTM technology is the next step in data density, allowing data centers to maximize their storage, especially in footprint- and power-constrained environments.

The 24TB / 22TB drive combines several innovative technologies including energy-assist magnetic recording (EAMR), HelioSeal®, triple-stage actuator (TSA) that improves TPI capability with greater control over the actuator arm, improved OptiNAND Technology and ArmorCacheTM. 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 energy-assisted magnetic recording (EAMR), triple-stage actuator (TSA), and HelioSeal enable high capacity with low power.

OptiNAND Technology Benefits

The Ultrastar DC HC580 is the newest-generation platform with OptiNAND technology, which integrates an iNAND® Universal Flash Storage (UFS) Embedded Flash Drive (EFD), with traditional spinning disk media. Western Digital's new 2.4TB/disk CMR areal density is used with its proven 10-disk platform, delivering up to 24TB1 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 event of an emergency power off (EPO) by increasing the amount of non-volatile memory (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 event occur. Power to a host system may be lost without warning; operating HDD's with write cache disabled (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 innovative feature provides enterprise power loss protection of data in WCE while increasing performance in WCD mode.
