4GB Memory Card
All About Memory Cards
Whether you enjoy snapping pictures or recording video, a memory card is a must for digital cameras and cell phones. Your camera may well come with some built in memory or perhaps a 32MB memory card but we all know that's not good enough. A 4GB memory card, or larger, can make life much easier.
We'll cover the basics about memory cards on this page and help you discover how many photos you'll be able to store before needing to download.
The Advantages and Disadvantages of a 4GB Memory Card
How Much Can a 4GB Memory Card Hold?
If you're a fairly new digital camera owner, then here are some tips to help you make a rough estimate as to which memory card will offer the storage you need.
Most people shoot their images in high quality JPEG. At this setting you will need 1/2x the number of camera megapixels to store a single image. This means that a 12 megapixel camera would use 6MB of memory to store a single image. Translated this means that a 512MB memory card would hold approximately 85 images at JPEG quality.
From this you can see that the more megapixels a camera has, the more memory it will require. (If you use TIFF or RAW file settings more memory would also be necessry)
As you can see a 4GB memory card on the other hand could handle roughly 666 images; enough to assure that you don't run out of space at an inopportune moment when the right shot appears. With today's more powerful cameras, higher capacity memory cards are often necessary.
The Types of Memory Cards

Affordable removable memory cards used in digital cameras and many other portable devices. It stands for Secure Digital memory cards. These are the most affordable. The 4GB memory card is the highest capacity of these cards.SDHC memory cards:
This is a higher capacity and newer version of the SD cards. Their capacity ranges from 4GB up to 32GB. Some older cameras are unable to make use of these cards.SDXC memory cards:
This is the newest in the line of removable memory cards. These "extended capacity" cards have up to 2TB of storage.MicroSD memory cards:
