Western Digital unveiled its latest data center hard disk drive (HDD) named the "Ultrastar DC HS760." This 20TB model features dual actuator technology, which enables parallel processing of data. 

Although the transfer speed specifications have yet to be released, it is expected to provide twice the sequential access speed compared to the previous single-actuator model, the Ultrastar DC HC560. The random access speed is also rumored to be 1.7 times faster. The Ultrastar DC HS760 features proprietary technologies such as OptiNAND, HelioSeal, and ePMR. OptiNAND is based on the iNAND embedded NAND flash, while HelioSeal fills the drive with helium, and ePMR increases the surface density of the platters.

The HDD has a SAS interface and uses a CMR recording method, with a rotation speed of 7,200 RPM, a 2.2TB platter capacity, a mean time between failures (MTBF) of 2.5 million hours, and a 5-year product warranty. Power consumption details have not been disclosed yet, but the drive is reported to have improved power efficiency by 37% compared to the previous model.
