Your comments are appreciated Andy, I'll reply with the results (in M bytes per second) including the version of OM 2007.2 used, test parameters used, the (?faster?) SD card I selected, when I get them. I'll compare the result with same test on the "stock" SD card that came with the Freerunner. Among all that is to work on, the test will be a fun and a good to know thing. Jim
