The SanDisk Extreme Pro 16 GB UDMA 7 CompactFlash memory card promises data transfer at speeds of up to 160MB/s! Note that there is more than one version of SanDisk Extreme Pro CF card on the market. And while they all have exactly the same design, data transfer speeds can be different. Be sure to check the packaging and retailer's spec sheets carefully before you buy to make sure you pick the right one! UDMA 7 is a protocol ensuring data transfer rates of up to 167 MB/s in both read and write modes. For this particular card, SanDisk announces maximum speeds of 160 MB/s (1067x) in read and write modes, which is near the limit of the UMDA 7 standard. Time to put that to the test!
