All SD Cards are Not all the same!!
And its not just the storage capacity that
sets them apart...

Most of us are using digital devices that store
data and images on SD (Secure Digital) cards. The SD card has
evolved over the past couple of years as the preferred format due to
its lower cost and smaller size as compared to compact flash, etc.
Most laptops or netbooks you purchase today come with a built in SD
card reader. Even if you purchase a micro SD card, it will usually
come with an adapter that will allow the micro card to be read in
any standard SD card reader.
But you may not know that there is more than
storage capacity that sets the better SD cards apart from the
cheaper ones....and the difference could be important as you begin
to use larger capacity cards! The key word here is "Class". If you
look at the image above, you will see the letter "C" with a number
in the center. In this case, it is the number 2. That means that SD
card is a Class 2 card which will read and transfer data at about 2
megabytes per second. The fastest SD cards available for standard
computers is the Class 10 card, transferring data at about 10 mb per
second. It will display a similar "C" on the label with the number
10 in it.
If you take lots of pictures or videos and
often transfer them to your computer, you will appreciate the much
faster speed of the Class 10 cards. You will often find the Class 2
or 4 cards on sale for much less than you would expect to pay, and
the ads will often not make it clear that you are purchasing a much
slower card. So be careful and look for the "C" with the number 10
in it to be sure you get the fastest transfer of you images that is
possible....
And if your digital data requirements are even
greater, you can purchase newer equipment that will transfer the
data even faster!
