Price / performance: Top 1 134

I bought this card recently as a backup, because who but often not enough for me that my Transcend 8GB 300x times.
Now the card is of course a lot slower, but go thanks to a sufficiently large cache of 50D also hereby even so some images in a row.
I photograph mainly animals / birds and use here also often the shutter mode (H) at 6.3 frames per second.
A picture (about 19 MB) is stored in 2.5 seconds, and the cache of the 50D takes up to 14 photos on, ergo you can use up the map about 15-16 images directly in a row. While there might be more like in some situations, but it is in my case also only a replacement card.
Also described by other read / write error so far I could not find.

For all those who either need a big enough fast card and those who simply need a more effective backup in case the card is schellere it out fully.

In any case I can wholeheartedly recommend.
