What is a Micro Memory Card?

In the world of technology, and high-tech devices, micro memory cards are almost as common as batteries. Flash media has made it possible to store vast amounts of data for use in a wide array of devices ranging from cell phones, to PDAs, laptops, digital cameras, etc.

Various types of SD (Secure Digital) cards (the most common being MicroSD) have found use in modern handheld phones and cameras. These cards typically offer anywhere between 1 GB and 32 GB of storage and have only gotten smaller overtime – like the devices they support. Innovation on the part of the manufacturers of SD cards has led to cards, the size of which used to be measurable in inches, being reduced to the size of a fingernail – all the while providing more and more memory.

Flash memory cards such as these enable mobile users to store thousands of songs on their typical handhelds – while allowing other device users similar luxuries. Photographers can now store just as many high-definition photographs without needing to worry about deleting pictures to make space for new ones. On that same note, the smart media card made it possible for digital cameras to really replace their obsolete (at least for personal use) film counterparts.

Another point to note is that micro memory cards are both reliable and speedy when it comes to data transfer. Copying an entire library of songs or photos to a memory card takes only a few minutes (at most) while transferring data from them - “read speed” – is even faster. These memory cards also have a purported life span of 10 to 100 years – far more than many storage media of the past decade – and are hardy enough to withstand typical wear and tear (repeated drops, etc.).

Finally, flash memory technology is fast-evolving and designers are finding ways to squeeze ever more information into rapidly decreasing physical space. Just over a decade ago, floppy disks were the most common storage medium for personal use. Modern micro memory cards can hold many thousand times the data of a floppy disk - which only goes to show just how much potential exists in flash media and how far its developers have come in such a short time. Nearly every modern phone and device supports flash media for storage and allows for productivity -in the case of a photographer being able to spend less time in studio and more time out taking pictures – while making for great entertainment when users can fit thousands of songs or desktop wallpapers onto their favorite phone or portable media player.
