It's been a little while since TDK
has made some news in the neverending race for next big hard drive breakthrough, but it looks like that could be changing fairly soon, with a recently revealed roadmap indicating that the company currently has some 640GB drive platters suitable for a 3.5-inch drive going through qualification tests by its OEMs. While nothing's obviously official just yet, TDK is reportedly looking to begin mass production of the platters in November of this year, which could pave the way for some four-platter, 2.5TB drives to debut as early as February of next year. As Register Hardware
points out, a five-platter, 3.2TB drive would also be possible, though somewhat less likely. We can dream, though.
