    I was just about to buy either a Seagate barricuda 7200.9 250 GB or the 7200.8 320 GB internal hard drive when I stumbled upon their 7200.10 320 GB drive with perpendicular recording...

    and now i'm stuck

    i kind of understand what perpendicular recording is thanks to hitachi's schoolhouse rock animation...haha, but how much better is it really? i've heard that by the end of this year seagate will pretty much make all their drives with perpendicular recording. anybody have experiences with the new drives by seagate or anyone else with perpendicular recording?

    if you haven't seen the animation, here it is http://www.hitachigst.com/hdd/research/images/pr%20images/Get_Perpendicular.swf

    Excellent animation - my one-year-old loved it!

    From what I've heard, it's as or more reliable than today's technologies but with much greater density - implying faster read speeds (write too, probably) as well as greater capacities. Seems like a win-win.

    Don't be stuck. It's a simple decision. Go ahead and buy it...Although you might want to wait until the prices come down later this year when Seagate will introduce 1 TB drives. Existing hard drives will be eventually replaced by those based on CPP technology and that's a fact. We can expect hard drives reaching if not exceeding 1 terabyte before the end of the year.

    The areal density limit offered by CPP will roughly double or triple the storage capacity of those based on conventional CIP drives.

    BTW, the title of your post doesn't make sense. "Perpendicular" refers to the way the data is stored on the platters. "IDE" refers to the interface between the computer and the hard drive. There is no direct relation between the two. It's like saying "radial tires vs. synthetic transmission fluid". They're both part of the drivetrain but have no direct effect on each other.

    The differences between the x.8, x.9, and x.10 lines is what you should focus on.

    FWIW, I wouldn't pay a premium for perpendicular recording unless I was purchasing a drive that was only available in that format. The 750 gig drive, for example. Not that there's anything wrong with it. It's just that the only significant advantage is being able to pack more data in the same physical space. No point in paying extra for that advantage unless you're actually making use of it. If it's cheaper or the same price, go for it.

    I'm sorry about that... as you can guess I'm new to hard drive terminology which was the reason for my post...
