What is a microSD card?

people who use portable electronic devices often want to store their data in a way that is portable. This is especially true for mobile phones, portable global positioning systems (GPS) and players and recorders of video and sound. One of the primary formats of these portable memory is the MicroSD card, which is one of the smallest memory cards on the market. It is produced by Sandisk, which lends the SD name; The second part of the name comes from the small size of the card.

Sandisk originally produced an SD card that was slightly larger than the microSD card. Then came the Minisd card, which was slightly smaller, and the microSD card, the smallest of all. Most technical measurements for a small card gave it to 15 x 11 x 1 mm (about 0.59 x 0.43 x 0.04 inches), which is roughly nail size.

MicroSD card is about Lometer's size of standard SD card, but can still be used with devices,that have SD cards with a special adapter. Portable audio and video players have SD card slots and some of the latest models even have smaller slots. When using a mobile phone or portable GPS device, the card is usually built into an electronic device. Some mobile phones or GPS followers have removable cards, but this feature is usually reserved for devices of a different nature, specifically those that are lent to expandable and folding needs of memory such as video and audio players.

The general idea of ​​SD cards is that they can have a memory ability of different quantities. The general amount of memory for one of these cards is 1 Gigabyte (GB), although microSD cards are also available in capacities of 128 megabytes (MB), 256 MB, 512 MB and 2 GB. The more data the card has, the more expensive it will be.

This increase in capacity does not mean that the corresponding physical size increases. Technology that allows you to make the hard disk drives of computerThey have reduced and reduced the hard disk and at the same time could hold more and more data, it also applies to this memory card. For example, the MicroSD 128 MB looks very similar to the 2 GB card, but the user notices the difference when he exchanges one for one in a digital audio player.
