Sometimes we buy stuff without actually reading in detail its uses, classifications, etc. Today Tech Habor takes a look at SD cards and how we can get the best out of them. SD cards are flash storage expansion cards we use to store information from almost every digital device today and it’s very important to know which type to buy, it’s speed and capabilities. Before you use or purchase an SD Card for personal or business use note these details.
There are wide discrepancies in memory card transmission speeds depending on the SD memory card manufacturer and brand. Varying speeds make it difficult to determine which card will provide reliable recording of streaming content. Recording video require a constant minimum write speed to ensure a smooth playback. The SD Association defines Speed Class standards indicated by speed symbols to help consumers decide what card will provide the required minimum performance for reliability. There are two kinds of speed indications regarding SD bus generation.
Speed Class and UHS Speed Class symbols indicate minimum writing performance to ensure smooth writing of streaming content such as video shooting. This is important mainly for camcorders, video recorders and other devices with video recording capabilities.
Speed Class designates minimum writing performance to record video. The Speed Classes defined by the SD Association are Class 2, 4, 6 and 10.

If your host device requires a Speed Class 6 SD memory card, you can use Speed Class 6 or 10 SD memory cards.
Digital format types and which SD Card best suits it
Some digital designers and normal users are well are of these features other are not and this seriously affects the quality of their work. For example after editing a video, picture or audio file it’s transferred onto just any SD card without knowing that not all of these flash storages can be used to hold some digital formats (jpeg, gift, mpeg4, avi, mkv) and after final production they see a lot of distortions in the work, that was displaying or previewing just fine on their PCs before the transfer .
For the smartphone or tablet users, if files on your SD Card is not able to display contents properly it not might be the fault of your phone but rather the SD card you just purchased.
