Seagate successfully delivered its portfolio of products to a broad base of customers and product shipments in the December quarter increased 24% on a year-over-year basis.

Products and Technology Developments

Seagate is well positioned to address rapidly evolving opportunities in cloud computing, mobile computing, hybrid and solid state storage.  We continue to provide the market with innovative storage solutions through technology research, product development and strategic investment.

Our research and development in HAMR (Heat Assisted Magnetic Recording) technology is designed to significantly extend hard drive areal density capacity and we demonstrated our first operational drive at the beginning of the quarter. We continue to lead in solid-state hybrid technology and are on our third generation for notebook drives, and we are expanding this technology into desktop and enterprise products. Our new 7mm 2.5-inch drive and recently demonstrated 5mm 2.5-inch drive position us well for the new thin and light systems.

In October, Seagate announced three new enterprise-class hard disk drives optimized for traditional data centers and emerging cloud infrastructures. The new line of drives provides the highest capacity-to-power ratios while ensuring consistent performance and high reliability. We also launched the first partner program for cloud builder called the Cloud Builder Alliance. The program is quickly adding new cloud companies of all sizes from around the world who are looking to utilize our expertise and tools for building an optimized cloud infrastructure.

In December, the company announced the Seagate Video 2.5-inch drive specifically engineered for use in 24/7 video applications.
