You can use
H2testw | heise Download to test how fast the card is, and to see if it is counterfeit. I run all my cards through this tool. Also, keep in mind that speeds also depend on your card reader. I've got a Samsung Pro microSD card which does 63 MB/s. For read speeds, most cards are pretty fast. The big difference is in the write speed.
I don't think there's a difference for write speed between JPEG and RAW, except for how fast can the camera process the images.
Congrats monochrome and Aslyfox!
Oh, and one of my latest acquisitions were something like 2-3 kilos of cheese from Galicia, and 10 liters of beer from there. The best in the world (at least those that I've tried). The beer needs to last a year, and some of it is meant as a present, lest you think I'm a drunkard.
