I have bought a Samsung 850 EVO 250GB yesterday and I am preparing to install Arch on it. But I have some questions before starting.
My SSD supports encryption (ENCRYPTION SUPPORT: AES 256-bit Encryption (Class 0) TCG/Opal IEEE1667 (Encrypted drive)). What does this mean? Can I encrypt the SSD from my BIOS (it suppots ATA password setup) in my PC and not set dm-crypt on it, or any third-party encryption software? I read about security problems with enabling SSD's TRIM function and dm-crypt/LUKS. If I make full-disk encryption with dm-crypt on my SSD and do Periodic TRIM, not Continuous, will this stop the "potential security implications" or it affects both, and the Periodic TRIM and the Continuous TRIM?
And do you have any extra tips about installing Arch on a SSD?
