My questions are partially about relative merit of different cards and partly
about issues, if any, of mixing and matching.
Context: K-1 with 2 card slots Shooting with RAW (DNG) images going to the
card in Slot 1, jpeg going to card in Slot 2.
Three different generations of SDXC cards: SanDisk Extreme 90 MB/s Lexar
Professional 633x 95 MB/s Lexar Professional 1000x 150 MB/s
In my simple mind, I believe that the three card types, in the order listed,
could be considered Fast, Faster, and Fastest.
Additional context: - I don’t shoot video - I seldom shoot a burst; when I do
the setting is Single Shot, but just triggering the shutter several times in
sequence e.g. as a duck flies by. - When traveling,the jpeg files are
downloaded to my iPad. That takes awhile, but even if card speed has anything
to do with it, a five minute vs ten minute time to download would be of no
consequence to me. - When at home, the RAW/DNG files are downloaded onto an
internal drive, copies to an external drive. I suspect that card speed is not
a limiting factor here, and again a few minutes difference is of no
consequence.
Question: In theory, would I expect to see any difference in the behavior of
K-1-A loaded with the Fast cards vs. K-1-B loaded with the Fastest cards?
E.g., if I do shoot a burst, will the buffer clear faster with a faster
card?
Question: Is there any reason not to mix-and-match? I pretty much always have
cards with the same speed rating in both card slots, but I don’t know if I am
being a bit too compulsive… And I would guess that if I did mix them, that it
would make sense (?) for the faster card to be placed in the slot where the
larger RAW files are being written.
Thanks!

Looking at the K-3, I have 3-32GB Sandisk cards that have a capacity of ~598 DNG
files:
Slot 1: SanDisk Extreme 80MB/s SDHC I U1 C10 32GB|8hr **
Slot 2: SanDisk Extreme 45MB/s SDHC I U1 C10 32GB
Grip: SanDisk Extreme PLUS 80MB/s SDHC I U1 C10 32GB
The K-1 I have 3-64GB SDXC cards that have a capacity of ~815 DNG files:
Slot 1: Sony U3 C10 95*MB/s SDXC I 64GB
Slot 2: Sony U3 C10 95*MB/s SDXC I 64GB
Grip: Lexar 64GB SDXC U1 C10 95MB/s 633x
And somewhere around here I've got a spare 96GB SDXC card. So, I guess Mix 'n
Match works fine. All the problems I've had are in my eye. The cameras do what
they're supposed to do. I think I've only had one card failure - the first 4GB
card I got for the *ist-D; Hoodman brand IIRC.
I have the two Sony cards in the K-1 because that's what my local pusher had
available at the trade show when he delivered it.
I talked to him when he was setting up the booth & he told me "It came in. Do
you want me to bring it to you tomorrow?" To which I, of course, answered "Yes!"
But with the higher capacity cards (32GB for K-3; 64GB for K-1) even shooting
DNG + JPEG (which I rarely do any longer; DNG alone seems to work well enough) I
rarely shoot enough to fill the cards and can't remember when I had to swap a
card out because I was running out of room.
With the K10D I started out with 4GB SD cards and for the the K20D I had a mix
of 8GB SD & SDHC cards. Nothing to do with the topic at hand, but I really
should get the *ist-D, K10D & K20D cameras out and exercise them.
Hell, I should get the PZ-1p cameras out and make sure they still work.
