Most of the electronics today use memory cards to store digital photos, mp3s, videos and other date. Different devices have different memory cards designed for them which varies in their shape, speed and capacity. This guide will provide basic information to help you find the best memory card for your devices.
Compatibility
That a memory card can enter into the slot of a device does not automatically mean it is compatible with it. All devices are designed to work with specific cards. It is therefore important to find out the exact card that a particular device can function with, before buying one.
Memory Cards Types
There are numerous types of memory cards. Not all of them are however available for sale today. Some of them are still useful for different gadgets.
There is the Secure Digital brand. This card actually looks like SDHC. The difference between them is that, while SD can store data up to 4GB, SDHC can store as much as 32GB and more. A backwards-compatibility feature also exists between them. An SDHC memory card slot could be substituted with an SD card, though there is no possibility of this happening the other way round.
MicroSD as well as MiniSD are lesser adaptations of Secure Digital cards. Devices like mobile phones as well as MP3 players use them. With an adapter, MicroSD can function properly in typical SD card slots.
Compact flash cards can carry up to 100GB. These are not as common as SD card, but they’re starting to gain popularity.
Memory Card Speed
The speed of cards determines the rate at which they exchange data with internal memories of devices. Typically, speed is 4-6 MB/s or 9-12 MB/s. Higher speed levels are more favorable for pictures taken in quick sequences.
Class 6 cards, which have a speed of 6MB/sec, are the least type required for shooting HD videos.
Class 10 (10MB/s) cards easily exceed the standard minimum needed for full HD movies.
For the maximum speed required for complete HD movies having professional quality, plus extremely high speed rate as well as high resolution digital cameras, UHS-Class 1 cards are the best.
Internal Memory
Every device may possess a specific amount of internal memory, similar to RAM in computers. Such storage is different from any memory card that could be plugged in. When the internal memory is not sufficient to hold data, the expansion slot of the device should be checked.
The acronyms NAND and NOR represent diverse ways memory cards can save and erase data. NOR flash memory, though no more in use, was appropriate for about 100,000 save and erase progressions. NAND can take up to 1,000,000 progressions. New cards ought to be bought once the limit is reached.
Care and Feeding
Bending, twisting, and damping, are all wrong ways of handling storage cards. Also, inserting them upside down or backwards could damage them. Proper care is necessary and they should be kept in places where they could easily be located.
