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.

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.

Digital Camera Batteries - Rechargeable is the Way to Go

There are few different kinds of digital camera batteries. Some cameras take rectangular-shaped batteries that are made specifically for the camera. Others use AA batteries or rechargeable batteries that are of the same shape. If you have this kind of camera, and you have ever tried to power it with regular AA batteries, you undoubtedly discovered how much power it takes to set off a powerful camera flash. You certainly need to invest in rechargeable batteries, a purchase that is more expensive than regular AA batteries, but that will pay for itself in the number of batteries it will prevent you from needing to buy.

Rechargeable batteries come with a charger so you can refill them with power ahead of when you need them. It is wise to buy two sets of rechargeable batteries and one charger so you can have a set in your camera while another is charging. You will never be out of power if you keep one set continually charged. Not only is there more than one style of battery for different kinds of digital cameras, there are varying materials that digital camera batteries are made out of. The most reliable kind available today is a lithium-ion battery. These are lightweight, long-lasting and recharge quickly.

Keep in mind that even if you keep two sets of batteries on hand, after you deplete one and transfer to the other one, it may not seem fully charged anymore. This is because batteries lose power when they sit around for a while after being charged. This does not harm the battery unless you fail to use your digital camera batteries for a few months. Otherwise, just be aware that when you go to use your batteries that were charged a few weeks ago, they may not be at their full capacity anymore. Go ahead and use them, refraining from recharging them again until they are nearly drained.

When digital camera batteries were first introduced, they were quite poor in maintaining their charge for more than a few pictures that required a flash. Today, cameras deplete their batteries much less quickly, but you can still preserve the life of your battery by charging it fully and using it until the display on the camera indicates that the battery is almost empty. Avoid letting your battery run completely out until it forces the camera to turn off. This can damage the battery if allowed to happen too frequently.
