4GB Memory Card

Updated on August 20, 2014

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

Spend less time downloading.Memory cards hold the photos (or video) that you take. Once the memory is full, you need to delete those images in order to take more. Naturally you don't want to loose those shots forever, so you download them before deleting so that you can preserve or print them. The more memory you have the less time you'll spend downloading. Clearly a 4GB card will hold far more images than a 32MB card. Eliminate the need for multiple memory cards.For the average person a 4GB card will suffice as far as storage space for an entire vacation. There's no need to bring along multiple cards. Of course, just to be sure, it never hurts to have one back up just in case of failure. PriceA 4GB memory card is a fairly affordable memory device and costs less than those with higher capacities. The possibility of failure.It can happen, a memory card can fail although it's somewhat rare. In such instances, it's particularly tragic if you have a large number of photos stored on the card. The risk in reality isn't much different than what people experienced with film and accidental exposure but indeed it is a potential drawback to cards with even higher capacity.

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

Just a few definitions for those who are new to memory cards:

SD 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:

MicroSD cards, as the name would imply are much smaller than SD cards. They are often used in cell phones and music players. They can be used in cameras that typically take an SD card only if a suitable adapter is available.

      The introduction of high definition video and high mega pixel photography would not have been possible if the SD organization had not come up with a faster storage system than the limited 2gb SD card standard. Visit jmveiwca

      So many to choose from you would have to get a multiple card reader accessory for all types of memory cards.

      The size of the card is relatively smaller than that of a hard disk. Over the years the physical sizes of the memory cards have grown smaller whereas their logical sizes have grown bigger. The first memory card was introduced as PCMCIA in 1990. It was mostly used in lap top computers. Thanks to its utility its demand grew substantially. CompactFlash was introduced in 1994 and was used in digital cameras. Compact6Flash got its competition from SmartMedia Card, introduced in 1996.
