    Why the SD became the "standard" of the memory cards

    in the history of memory cards have been many contenders to win the market, but only one type managed standardized to be technically and economically the most viable .

    the importance of memory cards in the age of digital photography is absolute, like the reel it was during the analog stage. You can not conceive the time before smartphones without them in many types existed. Moving from 30 to shoot photos without downloading 1000 or 2000 was revolutionary , both the economy and the possibility to put aside worries and absolutely immortalize every moment. To discuss how the SD (Secure Digital) cards and its derivatives became the de facto standard, it is necessary to know the previous context.

    When digital cameras emerged, was not too clear how they were to store pictures . The internal storage, and very expensive at the time, was tiny for the required amounts. Therefore, companies should seek external storage solutions. But the time was not much joy in that regard.

    The first bets were very conservative with cameras used archaic media such as floppy disks, CD-ROMs reduced size , etc. However, since 1994 there was, for example, the card format Compact Flash much smaller and possibilities that have made today is still in use in professional cameras size.

    from there began different proposals as SmartMedia, Toshiba, and miniature card appear, developed by Intel. The first, which gained more traction, faced limitations as 128 MB, which at the time was a very high figure, but eventually was scarce. The same problem Sony faced with Memory Stick 1998, so they had to release the Memory Stick Pro.

    The triumph of SD card is in its size, speed, ease of extraction and its universal goal against proprietary solutions

    at that time, he had already created the SD, based on memory cards existing MultiMedia Card (MMC) which, despite having a similar current SD size, came to serve expansion in mobile phones later years (though, especially with the equivalent reduced format to the current microSD, RS-MMC ). SD began to gain support and to show that proprietary standards in this regard were absurd and only brought complications for consumers. Despite this, Olympus and Fujifilm launched yet another format, xD-Picture Card , which was the last to fall in battle because of their underrepresentation in the market and the high cost of the cards.

    SD memory cards were small, fast and allow large storage capacities . In addition, any brand could and can adopt them and the cost to consumers is low, so this never rejected models for the cost of the cards, which is a situation that came to be when you acquire 1 GB of storage could be a disbursement of 100 €. In addition, companies that are part of the SD Association have always been commissioned to evolve the standard at a good pace.

    This is very noticeable in the way the type of SD card to your variant SDHC , which exceeded the barrier of 2 GB to 32, or later with SDXC , which increased the limit up to 2 TB , a figure that has not yet been reached. The same happened to cards small. First came the miniSD, which RS-MMC and Memory Stick Micro tried to stand up. They competed in different brands but the result ended up being similar to their older sisters. the appearance of the microSD ended all competition until these days

    About how much time they life is difficult to estimate. It seems that in the professional sector are very much alive and adapted to 4K, 8K and video 360 . In mobile terminals like the Galaxy S6 dispensed from the extension by cards, leaving only space for internal storage. This year, one of the strengths of the Galaxy S7 is retelling with microSD card reader. Despite progress there in internal NAND, it makes sense that the microSD continue to dominate, as more data (video in 4K) than ever before
