WD will demonstrate an ultra-fast 4 TB hybrid drive for gamers at the SATA-IO at Storage Visions 2015, January 4 to 5 in Las Vegas, NV. The prototype utilizes the SATA Express PCI-e interface, 4 TB 3.5-inch hybrid hard drive, and up to 128 GB solid state drive.
The two WD SATA Express interface demonstrations at Storage Visions 2015 will include commercially available motherboards from WD partners ASRock and Gigabyte. These systems will demonstrate cabled SATA Express PCI-e interconnect flexibility and configuration options for single-volume caching and RAID.
Heavy desktop usage scenarios will benefit from larger cache sizes (64 GB will be demonstrated) by enabling retention of key hot data across multiple applications, which improves overall performance. In WD's labs, WD's SATA Express 4 TB drive with 64 GB cache achieved a PCMark8 benchmark score of 4459, demonstrating near-SSD performance at an optimized GB-per-dollar value.
"WD is committed to working with the industry to push the boundaries of what you might expect from a traditional hard drive," said Matt Rutledge, senior vice president, Storage Technology, WD. "By moving to PCI Express, the industry marries the world's most popular storage bus with the world's most popular computer bus. This union provides a solid growth path to innovate new capability, while preserving the ability to plug legacy SATA drives into new SATA Express based computers."
