    How is it not reliable? I used full disk encryption for over a year on my current machine without issue. I decided to remove encryption when I realized I live somewhere where people feel safe leaving their doors unlocked, tools and bikes in front yards without them growing legs, and I like my system booting super fast.

    Did it recently with a btrfs drive. Didn't have any issues on my end.

    Please explain "not relible"?

    I've been using LUKS encryption for at least 5, maybe 8 yrs. No issues that weren't due to hardware failures. Whenever using whole partition encryption, like LUKS, having great backups is mandatory as any HW fault will lead to complete data loss. That is sorta the point for encryption of that type.

    The only slight trouble I had was in trying to resize a LUKS container that was holding PV, VG, and multiple LVs. It was always reliable, however.

    HOME directory encryption is deprecated for a number of reasons. The option was removed. It was stable, just slow and leaked metadata about the encrypted files.

    I've been using LUKS encryption on Android since v4 was released. Never had any issues with it either.

    Modern CPUs have built-in support for AES encryption so while there is a tiny performance hit with using encryption, if the defaults are used for LUKS, then that overhead is about 3%.
