    A lot of threads are starting to show up with questions about SD cards. So to make things simple here is a quick guide on the differences.

    When you are looking at the classes of the SD card you are basically looking at the write speed. Its really simple math. The numbers represent 1MB/s or 8Mbits/s. So if it says class 2 then its write speed is 2MB/s or 16Mbits/s.

    When looking at write speeds you need to keep a couple of things in mind. Most manufacturers do not recommend anything less than a class 4 or 6 for recording video. Some of them will even tell you its possible but they are against using less than class 6 for HD video. Now that phones are coming out that shoot 720P and 1080P video its important that you consider getting a class 6. If it shoots 1080P you are much better off at class 10.

    Read speeds of the cards are a different story and are often not indicated or even tested but are usually much faster than the write speeds.

    If you want to know the speed your card is reading and writing at here is the download you need. Its software for detecting counterfeits. H2testw 1.4 ? Gold
