A New Global Memory Card Standard 221

Lucas123 writes "The MultiMedia Card Association has approved a new memory card standard called the Multiple Interface Card (miCard). The card will make transferring pictures, songs, and other data between electronic gadgets and PCs easier. Twelve Taiwanese companies are preparing to manufacture the new miCard.

      And would SONY approve?

      That's a better question than you probably intended.

      This new memory card format marks a major shift in who's leading and shaping the market for electronics. The companies involved in setting this standard are all what used to be second-tier manufacturers - companies like Asustech and BenQ. In the past, it's been Sandisk, Sony, Siemens et al who've decided what shape our storage cards will be.

      I think it's pretty revealing that this group of second-tier Taiwanese manufacturers has come up with a unifying design instead of fragmenting the market even more, as has been the habit of Sony et al. Your DRM comment becomes more relevant when we realise it's this same group who've been providing us with inexpensive DVD players that support way more standards, with less restrictions than the old guard Euro/America/Japanese based electronics companies.

      It's probably a good sign for those of us who despise DRM.

            No ... the parent was talking about the difference between an MMC (that's "MultiMediaCard") and SD ("Secure Digital") cards and slots.

            Many people think that they are the same, but they are slightly different. MMC came first, and was a pretty neat format, but Sony and the other big music companies decided they hated it, because it didn't have built in features that made it DRM-friendly. So they "upgraded" the format and made SD, which includes an extra pin on the connector, an area of the card's memory that's not user-accessible (for storing the media keys, according to some never-widely-implemented DRM scheme they were cooking up), and a lock/unlock switch. They somehow got the manufacturers to kill MMC, by not producing many large-capacity cards for it, and replace it with SD.

            From a consumer's standpoint, we got a lock/unlock switch, higher prices for a while, and lost some capacity to the key-escrow area. (The latter is hardly noticed now, but it really sucked back on 32MB cards). MMC seems to have come back from the grave lately, though, mostly because of the reduced-size card implementations. (Maybe it's easier to implement in hardware and software than SD? I'm not clear on that.)

            These new memory cards are compatible to both USB and MMC, not SD. However, most SD card slots are backwards-compatible (IMO, that's a misnomer; SD was hardly a step "forwards" for anyone except the content monopolies) to MMC, so to the consumer it's "same difference."
            • by Moochman ( 54872 )
              Only possible diff it could make is if you have an exposed slot on the outside of a device that is built for SD. In that case it's probably wiser to go with SD, since it is thicker than the MMC and thereby more likely to block out dirt from getting inside the slot. This is exactly the case I had to consider when buying a new expansion card for my Cowon D2.

    I applaud the direct USB compatibility and the increased capacity, but don't kid us with claims of backward compatibility. Everyone already has 2-4GB MMC/CF/SD/XD cards in all their devices nowadays, and the industry needs to find an artificial reason to upgrade. Nothing more, nothing less.

      Of course, since most older MMC card devices can't read anything over 4GB, you'll still need to upgrade either your storage or your devices (or both).

      Why? Have your old devices stopped working? Mine have not and I've got more than enough flash cards for the forseeable future. Time marches on, sometimes things get better. My six year old CF based Cannon camera is still a champ, but it shipped with a 16MB card! 64 MB cards were just enough for a weekend, 256MB cards were nice and the 1GB card I have is strictly overkill. My newer of the same takes MMC and I knew it's limitations when I bought it. 1GB cards are enough to get as much video as the device has battery. I'm looking forward to HD video devices that will tax this new card.

      The big reason to move seems to be licensing. FTFA:

      Officials expect local companies to save $40 million in licensing fees thanks to the card, in addition to profiting from sales. Taiwanese companies will not have to pay royalties to make miCards or related technology.

      Slam, that's a lot of money. Hopefully, they see the same logic for OGG and friends. I'd really like it if my next camera did not come with a CD full of Windoze shit and that everything worked out of the box.

        Maybe with your devices. My camera will shoot several 1GB cards on a single charge, more if I use the right lenses (ie no image stabilisation, or if I am careful about how I use auto focus). A 1GB card gives me around 90 8-megapixel shots, which can be enough for a month or enough for an hour, depending on what I'm shooting and why I'm shooting.

        I can imagine professional gear will already start to tax these cards - Hasselblad already attach a hard drive to their cameras...

      This is the upgrade of the MMC standard to beyond 8G. That was "planned obsolescence" in the sense that everybody knew that eventually, we'd need a new standard for that. But every other flash standard has done the same because it didn't make sense to design a standard for 4G+ cards in the days of 8M and 16M cards.

      "Backwards compatibility" means that you can use your old cards in new devices conforming with the new standard. They also gave you a small card format and direct USB compatibility. Those are nice features; if they didn't care about backwards compatibility, they could just have chosen a new, small format that was incompatible with all your old cards.
  • Please, lets do something other than FAT.
    • FAT is ubiquitous and can be read by nearly all operating systems, so it is hard to displace. However, given such a high capacity, these cards will have many video recording applications and hence something besides FAT is needed because of the 4GB limit. I doubt the format is a problem because you'll be able to just format it to whatever you need.
      • Anything newer than Windows 95 OSR2 (with the irritating exception of NT 4) supports FAT32, including most Free operating systems. This allows partitions of 64GB or more, although starts to have quite a large minimum allocation unit size at these sizes.
    • There's always RAW. But personally I prefer to have my meat trimmed and cooked.
    • udf is the closest thing to a more modern universally supported fs. http://en.wikipedia.org/wiki/Universal_Disk_Format [wikipedia.org] The only big issue is that XP can't write to it. (Mac, Linux and many other OS's can read and write udf, atleast MS is finally coming to the party with read write in Vista.)

      Many posters are commenting here that FAT works across all operating systems and that's why it's being used. If these manufacturers came out with a new file system specification (say, based on BSD UFS), I doubt it would be a big deal for Microsoft, Apple, and the Linux Kernel developers to include it in there.

      The reasons we are stuck with FAT is:
      1. Simplicity. This is huge for embedded devices (IE, the things that do the writing to all of these cards). A read-only FAT driver can be implemented in a few kilobytes of (compiled) code. It requires trivial amounts of memory to operate (only a few hundred bytes). I've written a bootloader for an embedded product that could load an OS from a FAT partition and it was under 10 kilobytes. A read-write implementation is not much bigger and the memory requirements are similarly trivial. No other major file system out there can claim this. Particularly, modern file systems like NTFS require huge amounts of memory (comparatively) due to the complex structures they need to maintain, and have massive, complex code to read and write.

      2. Reliability. I know this seems counterintuitive for such a lousy file system, but FAT is fairly resilient both to power failures (or card yanks), and more subtle corruption such as bad drivers or media defects. Sure, it may corrupt and lose your file, but it very rarely destroys the entire file system and lose the rest of the files on there. This is again because of the simplicity of the structures and the fact that very little needs to change on disk when a modification is made. Remember how many times Windows 95 crashed? How many times of that did you get major FS damage? Compare and contrast with Ext2.

      So, yes, FAT is a terrible file system compared to modern ones. But there's a reason everyone uses it.

It's not the first card to offer USB compatibility. There are standard SD cards that can fold in half to present a USB connector to the user, but that's not a standard.

        More like a thicker version (presumably to fit nicely between the contacts and the edge of a USB slot) of a mini-SD I think. I have a micro-SD here, and it is not only much thinner, but much narrower as well. SD adapaters for micro-SD have their own contacts, with the micro-SD fitting inside. This one appears to just be plastic to fill the gap, so presumably you could use it without an adapter in a pinch, if you have a steady hand.

    I think it's great that SD/MMC has taken hold as a "standard" of sorts. CF was once the king, but is too big by today's standards. SDMMC is good because it's not TOO small (i.e., I'd expect my own mother to lose a microSD card but not an SD card), and it has a wide range of applications like SDIO cards for wi-fi and other uses. And, the adapters for micro/miniSD make sense too.

        Plus, if you have the need to swap cards between devices, I think that CF's large size actually makes it *more* convenient. miniSD, and now this new miCard business are great for cell phones and all, but for all practical concerns, they're far too small to be practical in general use (ie. you'll lose them).

    We don't need another standard. A few days ago at Wal Mart I saw Wii-branded product that is really slick. It is an SD card, but the back of the card has been notched out so that the last few millimeters are the width of the little PCB that is in the connector part of USB. So the card fits in SD slots as normal, and the back side can be directly plugged into a USB slot.

    Here it is. [walmart.com]

    Here is a similar product [engadget.com] with a slide on sleeve. I assume that might be needed for physical compatibility with some SD slots?

    Here is a SanDisk combo SD / USB memory card [engadget.com], but I don't like it as well because it has moving parts which can break.

    These products are pure genius. Personally, I think the SD standard should be updated to increase supported capacity, so we can use a ubiquitous form factor long into the future. I don't know about the rest of you, but I have these worthless PCMCIA memory cards lying around, which I replaced with now worthless CF memory cards, which I've now replaced with SD. I don't want another change, and we don't need anything smaller than Micro-SD. So only bandwidth and capacity need to increase, which the SD standard can be modified to support (while maintaining backwards compatibility) as the technology improves.

Why is that? Why couldn't they just use Flash o
    • MMC cards are the predecessor to SD cards, and share a similar interface. SD is basically MMC with extra features, including support for an early DRM scheme, thus the name 'secure digital'. SD cards are usually slightly thicker than MMC cards, so MMC would go in SD, but not vice versa.

      So you ask why they don't use CF or SD; in effect they ARE using the SD form factor, or at least its compatible predecessor. Anything that reads SD or MMC should read the new micard format, though SD has a 2GB limit IIRC. Depe

    What the industry really needs is a memory card standard that is totally open with absolutely no fees required to produce memory cards, card readers or software for it (unlike SD where you need to pay license fees). Or failing that, develop a standard where you only need to pay license frees if you are producing the physical hardware (i.e. the memory card or socket) and where the software is totally open. Motorola for example were caught between a rock and a hard place a while back because they had released a phone with a driver for the included SD slot built into the linux kernel instead of being a module and were stuck between "GPL violation" and "violating the SD association NDAs" (at the time they had to choose "GPL violation". It was all cleared up when the SD card people were convinced to release the "simplified specs" and Motorola could release the code in question)

Solutions are obvious if one only has the optical power to observe them over the horizon. -- K.A. Arsdall
