Specifics of hard drive data encryption
by Arct1c_f0x from LinuxQuestions.org on (#52D07)
I want all my drives encrypted however I'm also concerned about the longevity of my drives. I have Debian10 so I use LUKS to encrypt drives.
To my knowledge, how LUKS works is that it encrypts all data on the entire drive until you enter the proper passkey as which time all the data on the drive is unencrypted. Does this not greatly reduce the life of the drive through the constant writing and rewriting that takes place every time you enter the pass key and all the data is unencrypted and then reencrypted when you unmount the filesystem?
Perhaps what I'm asking is a very dumb question as I am overlooking something or just plain ignorant of some information I am missing.
Thanks in advance for the help!
