Hi guys.


I've always used Sandisk Ultra4gb memory cards on my Xsi (I've got 3)and they seem to be perfectly ok. I've finally usedtheUltra8gb card I purchased a while back and it seems to be incredibly slow. With the 4 gb it'll put a raw file on around 1 per second once thecameras buffer is fullbut the 8 gb card seems to only manage 1 file every 3 or 4 seconds. Quite a difference and really annoying when I'm using it.


Both say they are the same speed so why the difference?


Sorry this is such a dull query but any advice would be appreciated.
