Store More Using 16GB Memory Cards for Digital Cameras
Digital cameras can capture pictures and video in astounding quality. For this level of quality to be possible, they must have a way to store all the data. SanDisk memory cards offer a convenient way to store and transfer your digital images.What types of SD cards are there?
There are three types of Secure Digital memory cards offered by SanDisk: the regular SD cards, Secure Digital High Capacity (SDHC) cards, and Secure Digital eXtended Capacity (SDXC) cards. The main difference between each of these designs is the amount of storage that each is capable of supporting:
- SD: These are the original design. They can contain anywhere up to 2GB of internal storage.
- SDHC: Cards of this design are made to hold between 2GB and 32GB.
- SDXC: These cards are able to hold as much as 2TB of data.
The speed rating describes how quickly the memory card is able to read and write data to its internal memory. While individual cards vary in the speeds they reach, the rating that each has represents the bare minimum that they maintain under all circumstances. However, this is usually much lower than their peak speeds. For instance, a Class 10 memory card with a minimum speed of 10MB/s may be capable of reaching as much as 80MB/s in certain operating conditions:
- Class ratings: The first speed ratings were class ratings. The different class ratings include Class 2, Class 4, and Class 10, which have minimum data-transfer rates of 2, 4, and 10MB/s, respectively.
- Ultra High Speed (UHS) ratings: When cameras first became capable of recording 4K video, new speed ratings were created for the cards. UHS-rated memory cards have minimum transfer rates of 10MB/s or 30MB/s, depending on whether the card is a U1 or U3 type
- Video speed class: Memory cards rated on this scale are on the upper end of data transfer speeds. The number in a VHC rating stands for the MB/s that the memory card is able to maintain.
The miniSD is approximately half of the size of the original, and the microSD is even smaller. The small size of microSD memory cards makes them a commonly used method for expanding the storage capacity of smartphones. Both miniSD and microSD memory cards are available in SDHC format, and microSD can also support SDXC formatting. An SDXC microSD card can support upward of 64GB of storage, with 32GB being a common size that is convenient for use in many devices.Content provided for informational purposes only. eBay is not affiliated with or endorsed by SanDisk.
