Micro SD Card

Due to the growing trend of miniaturization, particularly in the mobile or portable device sector, the need for smaller storage media has subsequently become more pressing. But that is not all; consumers also look for media that can provide ample security, high read-write speeds, and sufficiently large capacities.

With the challenge set, memory card manufacturers have answered back with the development of the Micro SD card. This card is just a fourth of the size of the already small SD card and provides enough storage and speed for highly-demanding devices. What’s more, the micro SD card still retains the security features of regular SD cards. All these qualities have earned the nod of cell phone manufacturers, which is the reason why many phones support it. Other devices that use it are GPS handhelds, digital audio players, and some digital cameras.

The typical dimensions of a Micro SD card is 11mm x 15mm x 1mm. It has a mass of only 0.27 grams, the lightest of all memory cards. The maximum capacity is at 128 MB, quite small compared to regular sized cards. However, this is mostly sufficient for non-power users. The speeds of these cards are around 100 Mbps, which are at par to many other memory card varieties using the same flash technology.
