MMC or Multimedia Cards come in different shapes and sizes, but the most commonly used one nowadays is the Secure Digital card or SD card for short. Most of these cards have labels or markings on them that would, for the trained eye at least, give a user an overview of an MMC’s feature set by merely glancing on it. In this post, we’ll give you guys an overview on the six (6) markings that are often printed on an SD card’s label, what these symbols/values stand for and how it can help you in choosing the right SD card for your needs. Storage Capacity – This is probably the most common marking that you’ll see on an SD card. This indicates the storage spaces that a certain card can hold. However, do note that as with all storage devices, expect that the actual (usable) storage space that you’ll get is lesser than the indicated capacity on the card. Write-protect Logo – Another marking that you'll usually see on an SD card is the write-protect symbol, often seen on the left side of the card with an accompanying arrow-down label. In order to use the SD card, make sure that the tiny lever is at the top of the symbol which signifies that it’s unlocked and is not write-protected.
