[Leica] M8.2 SD card test results

[henningw at archiphoto.com (Henning Wulff)]

I also only shoot RAW. The speed differenes are considerable; I only 
need the RAW file and will gladly give up the B&W jpeg (useless 
afterwards anyway) for speed.

There are two Sandisk Extreme III cards. One slower, one faster. The 
Transcend cards are faster than the slower, slower than the faster 
Sandisk and a lot less expensive than either.

Fastest are the 2Gb 30Mb/sec Sandisk cards. Smaller cards are faster.
