SanDisk SDCFXS-016G-X46 Extreme 16GB CompactFlash memory card up to 120MB UDMA7 / sec. Read (Personal Computers)
I could only do not believe, more favorable than an EXTREME 60 / MB / s - but worlds faster. Writing: (EOS 5D Mark III with a 1/800 / s) EXTREME 16GB (60MB / s) - about 16 RAWs in a row ... Transcend 16GB 600x - about 17 RAWs in a row ... EXTREME 16G
