Unless you have a specific need for the capacity on one card, I can't see much
point. You pay extra per GB.
I just added a couple of 32 GB UHS-1 cards to my menagerie for $12.95 @. That's
40¢/GB, vs. 57¢.
I have four 64 GB SD cards, and they have more than enough capacity for my needs. If I put a clean one in each of my
primary cameras, I can go on one of our month+ trips and never have to change a card.
It may help to know what you are paying for.
The headline ad numbers don't mean much. 40, 45, 90, whatever, MB/S labels
refer to READ speeds.
Class 10 is a WRITE speed spec. Name brand cards are all going to write at about the same speed in older cameras that
don't support UHS-I.
UHS-1 is a WRITE speed spec. Name brand cards are all going to write at about the same speed in all but a few of the
latest cameras that can take use UHS-II.
The EVO and EVO+ are about small block, random read/write speeds, important for some applications, but meaningless for
your use (and mine).
I am not convinced that micro cards with adapters are the best choice for SD card cameras. It adds two extra layers of
contacts to get dirty, damp, etc. The big SD contacts seem pretty reliable, especially in sealed cameras like the OMDs.
I seem to recall having to remove, wipe and re-seat in other cameras once or maybe twice in the past. The micro contacts
are much smaller, so, together with the extra layers of contacts, seem likely to be less reliable in the field.
I do know I've had to remove a lens and wipe contacts a fair number of times over the years. Last year, in some serious
heat, while hiking and sweating, the iPhone in my belt holster stopped working - steamy SIM card contacts.
Sony and FujiFilm are still selling 40-45 MB/S labeled read speed cards for less than the faster to read cards. I've not
run a test, but the 'slow' cards still download fast on my USB 3.0 reader. The ones I mention above are Sony 40 MB/S
cards. I also have a couple of Fujis. Both work perfectly.
