SDXC versus Micro SDXC cards

I know there has been a thread on this subject before, but what's you're latest experiences with using SDXC versus MicroSDXC cards. With my K3 and K1 and K1 II, I've been using SanDisk Ultra and Extreme PLUS 64 and 128 GB cards without any issues (not tried any micro SDXC cards in the K1's). My K3 has been using the SDXC Micro Ultra 64 GB micro cards without any issues.

Has anyone move up to the 256 GB Cards with any issues?

Thanks in advance...

I have read warnings about using the micro cards

mainly due to the fear that it is two parts and could fail on that issue

I have never had a problem with any of mine

I just bought 2 of the 256 GB Cards but they are destined for insertion into a nook and a small 10 inch lap top, not the cameras

Ricoh does not recommend using microSD cards.

K-3 | FAQ | Support | RICOH IMAGING
Q: Can a miniSD Card or microSD card be used through a memory card adapter?
A: Proper operation of a memory card used through an adapter cannot be guaranteed.
Use a regular SD Memory Card (SD/SDHC/SDXC).

I have a Micro SD card around here somewhere. The one time I tried it in a camera, years ago, I got write errors halfway through the day and had to reseat it in the adapter. And that was the LAST time I used a Micro SD card in a camera. I'm sure some adapters do not have any problems, but I can understand Ricoh wanting to avoid the whole issue.

it will be interesting to see what the folks who comment will say

I use the micro type almost exclusively

I have had zero failures

I do not separate the cards but keep them together

this won't be a scientific test of any sort

but I am curious what members' real life experiences have been

I have never had an issue with several micro cards in multiple cameras, but I did buy two new Full sized cards for my K-1 from Hunts Camera.

Yes lost the images on a micro sd card due to file corruption. The card formatted fine and seem to write after that. Just to big of a chance, I throw the micro sd card away have never even thought about doing it again. I leave the image Russian roulette to someone else.

It would seem that the direct contact of the regular size SD card in the slot would be more efficient.

I have never tried them in my K3II. My last trip to CostCo I did see the 256 gb cards. I was really temped to get them. However I have 2 64 gb cards in now. They can really hold a lot of shots. I am not sure I am brave enough to try to fill up a 256 card and hope I can download with no problem. I would rather have several 64 cards.

How about anyone else?

I have two old 8Gb micro-SD cards with two different adaptors.

One adaptor is electrically totally reliable, but the "Protect" switch is so loose it had the habit of switching itself on (write-protecting the card) when I re-inserted it into the camera. A drop of glue fixed that! The other adaptor requires frequent re-seating if it's to be use as anything other than a container to carry the micro-SD card, so it only rarely finds it's way into a camera.

For me, the concept is now mostly redundant as I've just "upgraded" with a couple of s/h "class 10" full-size SDHC cards which give me both reliability and increased performance

I usually use dual 128GB SDXC cards in my K-3 and haven't had a problem and have them set up to mirror. This summer as a faily went out to Colorado and thought about getting another pair of 128GB or 256GB regular SDXC cards but gave the 256GB microSDXC cards a try from microcenter. They are a bit slower than the full size SanDisk 128s I usually use but worked fine on the trip. I don't think I will use the micro center 256GB cards are primary ones but for spares I will probably keep them around. The price difference between large capacity regular SDXC and the same size microSDXC is surprisingly large even from the same manufacturer.

The write protect/read-only tab does nothing when using an adapter. You can still write to and delete files off the microSD card even with the tab in the read-only position.
