Does anyone have any specifications for the bus speed for the SD cards
in our DSLR bodies? Under the rubric of Class 10 cards, different cards
are sold with different data rates. My recent purchases vary from 40 to
90 MbPS. The last time I bought cards, boosting speed from 40 to 80 or
90 cost about as much as going from 32 to 64 GB.
In addition to the speed to transfer the raw files from the buffer to
the card, there is also the speed to process the raw files, so while the
bus might in theory be able to handle 120 MbPS, the system might not
work any faster with a 90M card than with an 80M card.
Has anyone done any specific experimentation on where diminishing
returns come into play on recent bodies (K-5, K-3 ...)?
