In today's world of high-speed data transfers, cameras and their memory cards have been relatively left behind. But, Sony have stopped that with the Sony XQD memory card, based on the PCI-Express specification, the XQD format is aimed at improving digital image capture speed and performance.
It is capable of capturing up to 100 frames in RAW format in continuous shooting mode. Sporting write speeds of 125MB/sec, and theoretical maximum write speeds of 5Gb/s, or roughly 600MB/sec. You can see how this is exciting for photographers. Director of consumer media for Sony Electronics, Viviano Cantu, says:
Advanced shooters want to capture the moment in the highest quality possible, and that often means dealing with massive files like RAW images. Memory card technology has done a great job of keeping pace, but these new cards give an entirely new meaning to speed and performance.
