For a long time, I held my precious 4GB SD card in high regard as one of the largest capacity on the market. When I realized 8GB and 16GB capacity SD cards were common file storing tools, I felt like I had been living in the Dark Ages. In an attempt to set the record straight about SD cards and clear up misconceptions, I compiled information and tackled some of the most common questions related to the SD card.
What is an SD Card?
SD stands for Secure Digital. It was originally developed by SanDisk. It is a memory card compatible with portable computers, mobile devices, cameras and a wide range of other modern tech products. The Secure Digital standard is a brand kept up to par by the SD Card Association (SDA). There are over 400 brands associated with a wide range of product categories and more than 8,000 models of these devices.
What is Secure Digital Format
The Secure Digital format is made up of four card families, specifically High-Capacity (SDHC), Standard-Capacity (SDSC), eXtended-Capacity (SDXC), and SDIO. All four of these cards come in three standard forms, original size, mini, and micro. Various adapters make SD cards compatible with devices originally intended only for miniSD, Memory Stick Duo, and USB cards. Without these adaptors, SD Cards are not universally compatible. The SD Card and SDHC share similar functionality but different format, so not all devices are compatible with the higher capacity SDHC. The fun facts come into play when assessing how much memories these puppies can hold.
How Much Data Can an SD Card Store?
The SDHC card can hold the largest amount of data, in some cases up to 32GB which is the highest possible memory capacity. Prior to the construction of the SDHC card, the largest capacity card vendors produced was a 1 GB SDSC card. SDHC cards are virtually the same as standard-capacity SD cards (SDSC), except for the fact that they are exceptionally large, and not mutually compatible with all the same types of devices.
What is the Importance of SD Class?
SD class ratings are based on read and write speed. Class 2 and 4 are the most common ones and classes 6 through 10 are the highest standard available in the market. The number tells the megabytes per second in which the card performs its task. Capacity size of the card has nothing to do with the class of the card. A 4GB SD can be class 10 and a 32GB card can be class 2; but whatever the market price, class 10 cards will always be substantially more expensive than the lower classes.
What is the future of SD?
There is really no telling what’s in store for the future of the SD card. Common sense says, a bite sized disk packing a world of data will become even more bite sized and pack an even bigger punch, but by then it could be identified as something completely different. The only guarantee is that SanDisk will play a major role in the future of secure digital products. This makes the possibilities both infinite and infinitely intriguing.
