- - KIOXIA EXCERIA HIGH ENDURANCE (BiCS FLASH™) Max. Write Speed(s):
– 32G µSDHC ≤ 30 MB/s (similar to my current Samsung PRO Endurance card)
– 64G/128G µSDXC ≤ 65 MB/s
– 256G µSDXC ≤ 85 MB/s
- - KIOXIA EXCERIA PLUS Max. Write Speed(s):
– 32G µSDHC, 64G/128G µSDXC ≤ 65 MB/s
– 256G/512G µSDXC ≤ 85 MB/s
Yesterday I compared above microSD cards and asked myself why would be to recommend above two (within this thread)? But rather I’d like to rethink here why, or actually just go ahead and buy (preferably 
) ordinary (simple) microSD card like KIOXIA EXCERIA with following (deducted) feature:
Is it support for CPRM an important consideration (before buying an high-capacity µSD card) for all of our potential (personal) usage (if not public media content related) within a Linux phone? Is it KIOXIA EXCERIA indeed the one to recommend for non-CPRM content on Librem 5, non-CPRM private data requirement(s) friendly (up to someone’s own preference), as GNU site describes here (related to DRM, of course)?
Besides, I beleive that Micron i300 microSDXC cards (128GB to 1TB) are non-CPRM too (with CSD related value of 000b), yet another ones under SD specs version 6.10.
Well, sorry if bothering, but lollypop users probably like to stick, ensure they are using CPRM enabled microSD cards, just like here:
P.S. Feel free to link this post of mine somewhere else if here not 100% adequate, if anything needs to be added (perhaps, without investing into, sort of mandatory, CPRM security support) by admitting that I have no non-CPRM usage experience (and therefore asking for some quality opinion of yours).
