Digital Flash Cards - Data Storage on Flash Drives

Flash memory is a form of digital storage that is non-volatile, which means that it can retain its memory even when it is not powered. Digital flash cards are in wide use in memory, in USB flash drives, and in solid state drives. It is a read-only technology that is written and erased electrically. It is a very cost effective digital storage solution and because of that it is used in many devices like PDAs, cameras, laptops, and mobile phones. It is also becoming important to gaming systems in order to store saved games. It is better than other types of storage because it has fast read time, is electrically resistant, and can withstand temperature changes, pressure, and exposure to water. They last a long time and wear out only with erasure rather than usage.

Digital Flash Cards

Memory cards are probably most recognized as the little cards that are in digital cameras. They can hold varying amounts of pictures indefinitely. They can be used as temporary storage or as permanent storage. As long as there is a device to read the digital flash cards, they will pretty much last forever. They are extremely durable and reliable. Many devices have memory card ports for ease of access. Many desktop computers, laptops, printers and other devices have direct ports that allow nearly instant access to the pictures.

USB flash drives are known by many names including: flash drive, thumb drive, USB mass storage, etc. They consist of a flash drive with a USB connection and are rewritable. They have virtually replaced floppy disks for storage and portability. They are faster, smaller, and have greater capacity than floppy disks or even zip disks. Digital flash drives with USB are compatible with all computer operating systems and are even have applications on game systems like the Xbox, DVD players and smart phones.

Solid state drives, or SSD, are based on flash technology. They overcome the downfall of traditional hard drives: moving parts. SSD is valuable because it has no moving parts, it is quickly rewritable, and its capacity is far greater. They are still fairly new in the market and the applications are not as far reaching yet. They are still quite costly but will come down in price substantially in a year or so. They are being used mostly in computers, both desktop and laptop, and in external hard drives. Digital flash technology goes big with solid state drives.
