Was just looking at the Lexar 1000X CF cards at B&H and notice they now have 1066X cards too.
I have not researched them, but at first glance it seems that the difference is in the read and write speeds. The 1000X is 150MB/s (read) and 95MB/s (write) while the 1066X is 160MB/s and importantly 155MB/s.
I do get confused now and again, but weren't the 1000X cards also supposed to have a 150 or so write speed? Has something changed recently? I do not recall ever seeing these 1066X cards, and as it is such a strange number I wonder whether there has been some new legislation or something that has forced Lexar to make changes.
