Computer Makers Sued Over Hard Drive Size

FPCat writes "Finally, some one is doing something about one of my pet peeves. It seems a group of people are suing Apple, Dell, Gateway, HP, and others for misleading consumers about hard disk sizes. About time someone spoke up and said '1000 MB != 1 GB'" It's not much of a mystery to anyone who's up on industry practices, but it's similar to the way graphic displays are sized, cereal boxes are filled, and so on. Andy Rooney could have a field day with this one.

      In the computer world, metric prefixes are base 10 when they refer to time or a rate and base 2 when they refer to data size.

      Why?

      Times/rates use base 10 because, as is suggested earlier, it's the standard for the metric system. It makes sense to have the same prefixes mean the same thing across the board. Since time is arbitrary anyway, it makes sense to use the "regular" metric prefixes.

      Data size uses base 2 because of the way computers access memory. If you have a 8-bit address, you can have 256 chunks of memory. Likewise, if you have a 10-bit address, you can have 1024 chunks of memory. It takes the same number of address bits to have 1000 as it does to have 1024 and the hardware is generally simpler if you only deal with powers of 2. So since data-storage hardware is organized into groups that are powers of 2, it makes sense to use powers of 2 for the prefixes.

      The argument is very much similar to the argument against the English system. Both systems are used because you want simple conversions. I have 1,000 fluid drams of something. How many fluid ounces is that? Likewise, if you always end up with 1024 units of something, why would you use 1000 as your base instead of 1024? Does it make more sense to have all of your data coming in multiples of 1.024 or in multiples of 1?

      Hard drive manufacturers get away with it because hard drives aren't optimized in quite the same way as RAM. Hard drives are circular, so there's really very little benefit to making them contain 2^3n bits. You may end up dividing a hard drive in any event, and chances are your hard drive isn't exactly the maximum size your OS can handle. RAM, on the other hand, can easily be at the absolute maximum amount that a motherboard can handle. In that case, it makes sense to have 2^3n bits instead of 10^n bits. It needs the same size address and 2^3n is easier to manufacture, so ram always comes in powers of 2.

    I doubt it. Megabyte and Gigabyte are used in the computer industry to denote specific sizes, and have been for many years. This is like getting screwed over at a gas station because some dumbass decided that a gallon was equal to a pint because some Sumerian chicken measurements used a GAL prefix or something equally stupid.

    4. For CD-R, DVD-R/w, the industry defines 1024 MB = 1 GB

    No! CD-R uses binary prefixes and DVD-R uses decimal prefixes. Actually, in reality, both CD-R and DVD-R capacity labels are inaccurate under either the binary or the decimal interpretation, but you have to really be splitting hairs to notice.

    The exact expected capacity of normal sized CD-Rs (not counting overburning, yadda yadda) is as follows:

    • For 74 minute CD-Rs, the capacity is 74*60*44100*2*2*2048/2352 = 681984000 bytes, or 650.390625 binary MiB (exactly, no roundoff error).
    • For 80 minute CD-Rs, the capacity is 80*60*44100*2*2*2048/2352 = 737280000 bytes, or 703.125 binary MiB (again, this figure is exact, not rounded off).
    For DVD+/-R[W] media, the exact capacity is 4697620480 bytes, or just shy of 4.7 decimal GB. The capacity of a DVD-R is certainly nowhere near 4.7 binary GB.

  33. Re:The PC/HD makers redefined squat. by cje · · Score: 5, Insightful

    A gibibyte? Jesus. I'm aware that these are standard SI terms, but at some point you've got to let common sense step in.

    My production server at work has 24 gigabytes of RAM, by which I mean it has 24 x 1,024 x 1,024 x 1,024 bytes of RAM. I assume that you would claim this machine has 24 gibibytes of RAM, or that your desktop has 512 mebibytes of RAM, or that this particular object module is 72 kibibytes in size, then? If I started throwing around terms like that, people would look at me like I had gone completely batshit.

    "megabyte" and "gigabyte", as they pertain to computer storage, have always been based off of multiples of 1024. This is different than the traditional meanings of these prefixes, but that's a separate issue (and it's hardly new; they've been around for more than fifty years.) What is new is how HDD manufacturers have silently discarded the existing meanings in order to artificially inflate the size of their media. This is a phenomenon that has come about only in recent years (i.e., in the past 5 years or so.) The fact that these manufacturers protest "But look! Technically, we're right!" is not particularly meaningful to me. 40 MB hard drives used to be 40 x 1024 x 1024 bytes. 512 MB of RAM is still 512 x 1024 x 1024 bytes, the same as it's always been. And you claim that "HD makers redefined squat?"

    Another obvious example of this is CD-R versus DVD-R. A Yellow Book CD has a capacity of 650 MB, by which I mean 650 x 1024 x 1024 bytes, which is well above 650,000,000 bytes. DVD-R, on the other hand, which is advertised as a 4.7 GB medium, can only hold ~4.35 GB as gigabytes have traditionally been interpreted. So you've got one interpretation for CD-R, and another for DVD-R.

    Now, you can crow about SI units all you want, and you can go around talking about how many mebibytes of RAM your laptop has and how many kibibytes this e-mail attachment consumes, but if you don't see that there has been a recent redefinition of standard computer terminology by media manufacturers to hype their products, then you are being either naive or deliberately obtuse.

  34. Re:1024MB != 1GB by Elf-friend · · Score: 5, Interesting
    Unless I am wrong, though, the byte is not SI. The SI quantifiers only act as defined within the environment of SI, and so may act differently with bytes. In other words, the terms "kilobyte," "megabyte," "gigabyte," and "terabyte" have no defined SI meaning. This is similar to a U.S. hundredweight weighing 100 lbs., and an Imperial one weighing 112.

    The computer science community has accepted, by long use, the definition of 1KB=2^10 bytes. This means that, although it is inconsistent with the SI definitions of the quantifiers, this is a de facto industry standard; one which hardware manufacturers have intentionally defied for years. That this is not the SI meaning of those quantifiers is a moot point.

    Mega means "1 million". Computer scientists started using the term Mega to identify 2^20, which isn't actually 1 million....they were approximating. In this case, it's the computer scientists who gave an alternate meaning to a common numerical term...not HD manufacturers.
