TransFlash and microSD cards are functionally identical allowing either to operate in devices made for the other. The microSD removable miniaturized Secure Digital flash memory cards were originally named T-Flash or TF, abbreviations of TransFlash. While the new cards were designed especially for mobile phones, they are usually packaged with a miniSD adapter that provides compatibility with a standard SD memory card slot. The SDA adopted the miniSD card in 2003 as a small form factor extension to the SD card standard. The miniSD form was introduced at March 2003 CeBIT by SanDisk Corporation which announced and demonstrated it. Early samples of the SD card became available in the first quarter of 2000, with production quantities of 32 and 64 MB cards available three months later. The SD Association, headquartered in San Ramon, California, United States, started with about 30 companies and today consists of about 1,000 product manufacturers that make interoperable memory cards and devices. For this reason the D within the logo resembles an optical disc.Īt the 2000 Consumer Electronics Show (CES) trade show, the three companies announced the creation of the SD Association (SDA) to promote SD cards. The trademarked "SD" logo was originally developed for the Super Density Disc, which was the unsuccessful Toshiba entry in the DVD format war. Developers predicted that DRM would induce wide use by music suppliers concerned about piracy. It was designed to compete with the Memory Stick, a DRM product that Sony had released the year before. The card was derived from the MultiMediaCard (MMC) and provided digital rights management based on the Secure Digital Music Initiative (SDMI) standard and for the time, a high memory density. In 1999, SanDisk, Panasonic (Matsushita), and Toshiba agreed to develop and market the Secure Digital (SD) Memory Card. History 1999–2005: Creation and introduction of smaller formats The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility. SDA today has about 1,000 member companies. The companies also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards. The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products. The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita) and Toshiba as an improvement over MultiMediaCards (MMCs), and has become the industry standard. Secure Digital, officially abbreviated as SD, is a proprietary non-volatile flash memory card format developed by the SD Association (SDA) for use in portable devices. Just copy the NOOBS files onto it.Portable devices, such as digital cameras and mobile phones (including most smartphones) If you are using a brand new SD card you shouldn't have to use the Format step at all, it should be ready to roll. The advantage of using the SD card formatter over Windows' built-in formatting is that the only option is to format it as FAT and it will only let you format an SD card so there are fewer ways for a N00b to go wrong with the NOOBS instructions. (rather than splitting the SD card into a FAT16 '/boot' partition and an EXT3 Linux '/' partition. The NOOBS instructions are just formatting the whole card to FAT16, and copying a FAT16 based distro onto it. On first boot you should have an option to resize the EXT3 partition to fill whatever space your SD card has left. You are just laying down the image onto the new disk, making it an exact copy of the developer's disk. The Image files of all of the RPi distros contain a FAT16 partition and an EXT3 partition (versions of FAT and EXT might vary from distro to distro). If you have used DD, this is basically the same process. When you use something like Win32DiskImager to prepare an SD card, all you are doing is taking the image file of the distribution you want to use and applying that image to your SD card.
