About 256MB SD Camera Memory Cards

The most common storage technology for digital cameras is an SD card. These cards allow you to save pictures in a format that preserves all their details and then upload the files to your computer later on. Having one or more SD cards allows you to shoot as much as you want without worrying about running out of space.

Why use an SD card?

An SD card strikes a balance between the quality of the image file, the speed of transfer, and convenience. Wireless networking or Bluetooth tend to require either compression of the file, which means a loss of quality, or slow transfer speeds. On an SD card, you can simply slide it into the reader slot on the computer, and the files are available. A wire transfer is also slow and tends to require special software or a driver while an SD card is a plug and play.

How much space of SD card do you need?

The more video you take, the more memory space you need because video takes up a significant amount of space. Usually, pictures range from a few MB each to up to 50 MB for a large and high-resolution picture. You can adjust how much space each picture takes up by changing the quality settings in your camera. That will let you know how much storage you need and also how many cards you need. Keep in mind that it is easy to swap cards in and out, and the cards themselves are small. If you plan to carry several cards, you may want a case of some kind to keep them protected. On a 256MB memory card, you may be able to store a hundred photos or a few dozens depending on resolution.

Do SD cards have any unique features?

There is one particular extra feature that a digital card can have, and that is waterproofing. A waterproof camera should have a protected chamber for the SD card, but for safety, you should make sure that the card itself is waterproof. The packaging will explain how deep in water the digital card can go before it starts to suffer from damage. It might also say something about being splash-proof or water safe, which means it can handle a casual dunk or an accidental spray, but nothing more than that. Other memory card features include increased transfer speeds and higher storage capacity.
