Useful Tips On Purchasing A Memory Card
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.
Suitability
Even if a memory card fits into a slot on your devices doesn't necessarily mean it's compatible. Every digital camera or cell phone, etc., are designed to accept specific cards. Before looking, check your devices and find out which one are compatible with each device.
Memory Cards Types
Dozens of formats have been made but, not all of which are still available. These are some of those common formats which are presently used by consumer electronics
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.
Other smaller versions of secure digital cards are MicroSD and MiniSD. They are used for gadgets like MP3 players and cell phones. MicroSD cards can function well in normal SD card slots with the help of an adapter.
Compact flash cards can carry up to 100GB. These are not as common as SD card, but they're starting to gain popularity.
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 highest speed rating required for full HD movies with professional quality, as well as extremely high-speed and high resolution digital cameras, the most suitable storage cards to use are the UHS-Class 1 cards.
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.
NAND and NOR are acronyms which explain the different ways that memory cards can write and wipe away data. NOR flash memory used to be suitable for up to 100,000 write-and-erase sequences, though they are not in use anymore. NAND can be used for as much as 1,000,000 write-and-erase sequences. There will be need to purchase new memory cards once their limit is exceeded.
Care and Feeding
Wetting, twisting, and bending, are incorrect ways to handle storage cards. In addition, inserting them wrongly can spoil them. Therefore, they should be properly cared for and stored in places where they can be located easily.
