Ok seriously, this can't be that hard to figure out...
SD are now faster than CF cards, and just about the same price. I
know many of us have spent untold dollars on CF cards, so make
everyone happy. Put in a dual-slot SD/CF card reader in this baby.
Its not like there isn't enough room...SD readers are so tiny to
start with, then couple it to the CF card reader, and you wouldn't
even know it was there. Anybody complaining because they have the
freedom to choose which cards to use?
Ok, so then lets give them 1 more thing...lets give the camera the
ability to write to both cards simultaneously. I know it would
take a bit more processing power, and some unique architecture, but
its surely not out of our reach. This should basically be enough
to shoot at a rate of 15 mb/s, and assuming we get a buffer of say,
512 mb (cmon, I'm willing to pay for it), you could basically shoot
as many shots in a row as you like.
Lets see...
flow into buffer = 6 frames/second * 8 mb/raw frame = 48 mb/s
flow out of buffer = 10 mb/s (SD card) + 6 mb/s (CF card) = 16 mb/s
total flow of buffer = (48 - 16) mb/s = 32 mb/s
512 mb/(32 mb/s) = 16 seconds of continuous 6fps raw shooting = 96
frames.
96 frames * 8 mb = 768 mb
sooooo, if you have 1 512 pro CF card, and 1 512 high speed SD
card, and the ability to write to both at their capacities, you can
damn near shoot 100 frames of raw, at an amazing rate of 6 mb/s.
Anyone else like this idea? I know, I know, you are wasting huge
amounts of memory in seconds, and obviously, after this 16 secound
burst, your camera is going to be writing for a long time, but who
cares, you just cought 100 shots during a single play of the
football game...and thats a long play, if I might add. Now, to go
back and delete all the useless ones....well, thats a whole nother
issue.
How sweet would it be to be able to shoot 6 fps for 16 seconds????
I don't think many pro action photographers would be using Nikon
and Canon for long
