Just to add my 2 cents, I tested various 128 GB CF-cards recently, among them Komputerbay 1050x, SanDisk Extreme 120MB/s, Lexar Professional 1000x and Hama 150MB/s, but the only ones that I found reliable are the SanDisk Extreme Pro 160MB/s. 64GB cards seem to perform a whole lot better (understandable), the 128 GB models work much faster as FAT and rather unreliable formatted in ExFAT.
