Seagate has shipped the first 3.5-inch desktop hard drive employing Perpendicular Recording (PR). Perpendicular Recording is a technique used in hard drive design that adds capacity and speed. This new 3.5-inch desktop hard drive is the Seagate Cheetah 15K.5. Using PR, areal density has been doubled up to 73GB per platter for up to 300GB per drive. The drive spins at 15,000rpm, and has a sustained transfer rate of 125MB per second.

So basicly, the mp3 player would be the size of a ipod mini but be 10x more space.Humm, Maybe they will sell the idea to apple. Big bucks are to be made with this technolgy with the right marketing scheme.

Hmm... 3.5in = desktop drive, 2.5in = laptop drive. iPods use an even smaller hard drive which does not need to be as speedy. Cheetah drives are mostly commercialized in workstation and server markets. But given the advancement we could easily see Raptors in that range in the coming year or so.

"125MB per second" that's impossible! My ATA HD can hardly reach 12MB per second.
