Unfortunately my experience with KomputerBay cards was not that good, and I only bought them after hearing good things about them on this forum (I guess about half the time anyway).
My results with the KB 1000x 32GB 150MBps read/120 MBps write (stated) only proved to be 83MBps read/61Mbps (actual) write; purchased on Amazon (so could be fake? Maybe, I originally thought fake only on ebay, but later heard some fake on Amazon too).
These test were conducted on MBP USB 3.0 port and card reader and in camera itself with ML, with nearly exactly the same results (within tenths of a MBps).
