Seagate 7200.11 1.5TB HDD  (Source: Seagate)
Seagate 1.5TB HDD uses four platters

It has only been about a year and a half since the first 1TB hard drives began to hit the market -- Hitachi was the first to unveil its 1TB HDD in January of 2007.

Just this week Hitachi unveiled its second generation 1TB HDD with a 43% power savings compared to the first generation. The Hitachi drive uses three platters to get the 1TB capacity and save energy. Today, Seagate announced the world’s first 1.5TB desktop hard drive called the Barracuda 7200.11 1.5TB.

As you can gather by the name, the drive spins at 7,200 RPM and uses four platters to reach the massive 1.5TB capacity. Seagate says that this is the largest increase in storage capacity in the last 50-years and the 500GB increase in capacity is thanks to improved perpendicular magnetic recording technology.

Along with the 1.5TB 3.5-inch desktop HDD, Seagate also announced new 500GB 2.5-inch HDDs for use in notebooks. The 500GB notebook drives will ship in 5,400 and 7,200 rpm varieties. The drives are known as the Momentus 5400.6 and Momentus 7200.4 HDDs. The 5,400 RPM drive uses an 8MB cache and the 7,200 drive has a 16MB cache.

Seagate executive VP and general manager of Personal Computer Business Michael Wingert said in a statement, “Organizations and consumers of all kinds worldwide continue to create, share and consume digital content at levels never before seen, giving rise to new markets, new applications and demand for desktop and notebook computers with unprecedented storage capacity, performance and reliability. Seagate is committed to powering the next generation of computing today with the planet’s fastest, highest-capacity and most reliable storage solutions.”

Seagate announced in 2006 that it expected capacity of HDDs to hit 2.5TB by 2009. The Seagate 1TB HDD was announced a bit over a year ago in June 2007.
