memory card - Is there any reason to choose a standard size SDXC over Micro SDXC?

Stores offer both micro SDXC and standard size SDXC cards. The micro cards come with standard size adapters.

If the specs are otherwise absolutely identical, e.g.:

• SanDisk Extreme UHS-I/U3 Micro SDXC Memory Card, 64GB


• SanDisk Extreme UHS-I/U3 SDXC Memory Card, 64GB

is there any reason to choose the larger SDXC card over the micro? The only negatives of the micro would appear to be physical vulnerability: easier to lose and more physically fragile.

But I believe that from the camera's perspective, they're identical -- and the micro is a bit more future proof as I can use it in a wider range of devices, correct? Can anyone come up with a reason why the standard SDXC would be preferable?

For example, do standard size SDXC use larger process NAND memory cells or have better/more wear leveling or error correction? Or are they identical from a chip perspective and it's only the package that is different?

Answer

I've read that the performance is indeed comparable (at least from reputable vendors), so that makes the only real factors the form factor and the price.

I find using an adapter a mild inconvenience, since it's one more thing to worry about, but I don't think that's a big deal. I also don't think "future proofing" is a big deal either, since cards don't last forever anyway, and by the time you buy a device that only takes MicroSD, capacities will be much higher, and performance will be better, so you won't regret buying a new card. (Or, at least, cards of today's capacity and speed will cost peanuts.)

So, to me, that leaves price. Currently the prices for the cards you list are about $45 and $40, so, eh: five bucks / ten percent. Sooooo, I guess you could get the cheaper one plus a beer, or the more expensive one and call it a day; whichever suits your gut feeling better — and then feel secure that you didn't make a mistake either way.
