Full Answer

SD cards have a maximum capacity of approximately 32GB, while XD cards have a smaller capacity of 2GB. XD and SD memory cards are media storage devices commonly used in digital cameras. Cameras using an SD card can shoot higher-quality photos because it has a faster speed than the XD memory card. Excluding the micro and mini versions of the SD card, the XD memory card is much smaller in size. When purchasing a memory card, SD cards are the cheaper product. SD cards also have a feature called wear leveling. XD cards tend to lack this feature and do not last as long after the same level of usage. The micro and mini versions of the SD cards are ideal for mobile phones because of size and the amount of storage the card can offer. XD memory cards are only used by certain manufacturers. XD memory cards are not compatible with all types of cameras and other devices. SD cards are common in most electronics because of the card's storage space and varying size.

  • Q:

    How do flash memory cards work?

    A:

    Flash memory cards consist of large numbers of individual cells, each of which contains a set of transistors. Under normal circumstances, current flows between the transistors and into a drain. When a charge is applied to one of the transistors, the current flow gets blocked. The amount of current passing through the cell effectively flips it from a one to zero, allowing for the storage of binary data.
