I do not perform calculation of cpu power needed to check checksum. And I
though encrypting disk force bigger memory usage. If it is not the case (space
usage for encrypted partition), I do bad decision (my disk is unencrypted). If
encryption on OpenSUSE enforces bigger space usage, maybe allow to use
algorithm without bigger space usage than unencrypted data?
