XQD cards appeal to sports, photojournalism and wildlife photographers as they are able to keep up with the shooting speed of your camera which, in turn, clears the bufferBUFFERInternal camera memory used to cue images for saving to the memory card. This cueing is necessary due to the inherent writing speed limit of memory cards. When the buffer becomes full, it creates a bottleneck and the shooting rate reduces dramatically to compensate for the memory card speed limit. More professional cameras typically have much larger buffers which can cue a larger amount of images before the shooting rate is reduced. faster. These features make them perfect for high-definition camcorders and high-resolution digital cameras. In essence, their key benefits are providing fast read and write speeds, and high-capacity storage.
