Oh yes, I forgot to mention. It appears that the best bang for the buck
if you're using a Pentax camera, is this

which the afore mentioned website tested but not in the K-3II

The only website that I've found that even makes a pretense of
measuring the bus speed of cameras has the K-3 II at 37.2mb/s, using
cards that tested with often much higher write speeds, so you don't
really need to worry if that 90Mb/s is read or write speed, only if
the write speed exceeds the bus speed of your camera, which in the
case of the K-3II is a bit over 37Mb/s. So a card with a real write
speed of 40Mb/s would probably do.
The site that tested the K-3II is here with a comparison of a variety
of cards.

This group of tests was obviously done some time ago as a number of
the cards mentioned are no longer available in all storage sizes.
I haven't been able to find tests on a lot of less expensive cards,
and haven't really been looking since I can't seem to find a
reasonably priced and warrantied K-3 since last December, when I was
quite low on pennies, but it looked at the time that most, but not
all, major brand cards that were rated at 80-90Mb/s were at least
capable of 30Mb/s which would have very little effect on performance
in the K-3II, since it depends on depth of buffer a lot more than bus
speed for it's performance.
I'm still using a K-5II and I've only once, that I remember, run out
of buffer with that camera. I've been primarily using PNY cards.
They were cheap and available a number of places a while ago, and the
specifications were good for the price. I could probably replace them
with cards that were twice as fast in actual use for half the
price/MB, but the camera bus speed is more of an issue than the actual
throughput of the card.

It's been a while since I've purchased SD cards.
What is the current price/performance/quality sweet spot these days?
Ideally in make, model and size. And if someone bought cards in the
near past, a pointer to the item in the store would be fantastic.
I'm going to need to get a couple cards soon, and I'm hoping someone
else recently did the research, because the sweet spot tends to
change every month or two.
The last I checked you got the most storage for your money at about
64GB.
Some people are Sandisk, or nothing, others are happy with PNY,
Patriot etc. There are also other "name brands" that one could look at.
Also, the various speed ratings on SD cards are difficult to sort
out, at best. 90Mb/S isn't always 90 Megabits, there's also class 10
etc. With the sucky bus in the K-1, there's probably a certain point
where faster doesn't improve the camera's performance, but I can
always hope that new models will be better.
