I have a Nikon D5100 and currently use a class 6 SDHC memory card. Since I am still fairly new and use "RAW + JPEG" mode there is a lot of heavy writing to the memory card (not to mention quickly draining the battery).
Does the D5100 write to the memory card enough that I would get faster saving with a class 10 memory card?
As a reference, these are the minimum write speeds (as defined by The SD Association) for the various classes:
Class 2 2 MB/sec Class 4 4 MB/sec Class 6 6 MB/sec Class 10 10 MB/sec
