where can I get these?

are these SDXC cards compatible with SDHC readers (at lower speeds) ?

What does "3C life" mean? Feel dumb asking lol.

No.

I was asking myself the same question. Thanksfully, it seems the SDXC readers are backwards compatible to SDHC, look though these:

Newegg SDXC card reader search

I am not sure myself, but searching for the keywords SD and 3C brought me to an LLC called SD-3C. SD-3C is apparently a licensing company for SD card manufacturing formed by 3 companies Panasonic Corporation, SanDisk Corporation and Toshiba Corporation. To my understanding all companies who wish to manufacture SD cards must obtain a license through SD-3C.

It can depend. 99% of Android phones with MicroSD slots claim only SDHC (32GB) support, though a lot of them work with 64GB SDXC cards fine. I assume many independent readers are the same, there can't be that many controllers.

my phone is what i was thinking of when i asked, actually.
