Hitachi Promises 4-TB Hard Drives By 2011

zhang1983 writes "Hitachi says its researchers have successfully shrunken read heads in hard drives to the range of 30-50 nanometers. This will pave the way for quadrupling today's storage limits to 4 terabytes for desktop computers and 1 terabyte on laptops in 2011." Update: 10/15 10:39 GMT by KD : News.com has put up a writeup and a diagram of Hitachi's CPP-GMR head.

    4TB = 4096GB = 4,194,304MB
    however,
    in the 'hard drive' world, and everywhere else these days, we've been told that 1000MB=1GB and 1000GB=1TB, so 4TB = 4,000GB = 4,000,000MB.

    So what are we really getting?! if 1TB = 1,048,576MB, then 4TB = 4,194,304MB, so we are missing 194,304MB - which is the better part of 190GB right?

    Isn't the mixing of the 'new' SI units and good old binary values confusing? now someone needs to do the calculation for certain filesystems and not just arbitrary values.

    feel free to correct me if I am wrong, I wrote this before going to sleep.
