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.
OptiNAND improves drive resiliency in the event 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) reduces 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.
