Western Digital is planning to showcase a line of hybrid hard drives which will clock in at less than 5mm thick.
The company said that the drives combine standard 2.5in disc-based hardware with solid-state drive (SSD) components and will be offered through the company's WD brand, targeting the high-performance storage space.
According to WD, the drives will be roughly half the thickness of previous 2.5in models and would allow hardware vendors better flexibility when designing new ultrabook and thin-profile notebook systems.
"Mobile devices are becoming smaller, thinner, lighter and more responsive," said WD vice president of client storage Matt Rutledge.
"Working with our technology partners, WD has developed new 5mm hard drives that enable high capacity storage along with excellent performance and superior economics to allow our customers to expand their thin offerings."
The company hopes that the hybrid drives will prove popular in a notebook market which is increasingly looking to thinner designs as a way for matching the light weight and portability afforded by tablets.
Intel has put much of its marketing might into pushing its ultrabook platform, showcasing models developed by OEMs and putting research and development funds into advancing the brand. Apple has also sought to advance the market with its MacBook Air brand.
While the thin design of the lightweight notebook models have won rave reviews, the high price of components such as SSD hard drives has largely limited the ultrabook sales to the high-end and early adopter market segments.
