200x speed reaches the card certainly does not. It is rather to 120x-level and creates at current UDMA-enabled DSLR (without bottleneck) gerademal 14.8 MB / sec. A Sandisk III with 30MB / sec, however, creates real to this DSLR (such as 5D Mark II / 50D) and 30 MB / sec. The disclaimer "system dependent" and the product name 200X seem to me misleading. There are cheaper 32GB cards with better, real speed, at least in the mentioned environment.
