Hitachi plans to announce this week a massive 400GB hard drive, according to CNET News.com. “The new drive has a capacity of 400GB, spins at 7,200 revolutions per minute and uses ATA (Advanced Technology Attachment) interface technology, according to a source close to Hitachi. The drive can come with either the parallel ATA interface long used in desktop computers or the newer Serial ATA interface. Dubbed the Deskstar 7K400, the drive is being tested by manufacturers and could be in digital video recorder (DVR) products available to consumers later this year, the source said.”
