linux - SD cards and CPRM protection

Before buying an SD memory card, I'd like to know something more about the CPRM protection, in particular:

• Does CPRM influence the way I am supposed to access my own data? That is, does CPRM encrypt it? Could CPRM prevent me from accessing my own data?


• Is it possible to disable or eliminate CPRM from either the memory card or the card reader?


• Are there manufacturers selling CPRM-free SD memory cards?


• Is there any real alternative to CPRM-protected SD memory cards beside USB flash drives?



• Is Linux support for SD cards good?

Thanks.
