From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I will take that into consideration. I already encrypted my older laptop (hard drive) with LUKS. Is there something special, when it comes to encrypting SSD's? Do you experience speed losses of SSD after doing so?
every mobile device I ever owned is encrypted and protected with a reasonably secure pass-phrase so losing it is no big deal. it is conceivable someone could forensic the shit out of my setup but that is highly unlikely; it's far more likely it'll get wiped and sold or parted out.
I've done no benchmarks but I haven't experienced any issues ever. the oldest linux device I own is a 2011 MBP (i7-2635qm, so quadcore) and I don't perceive any speed degradation; it's possible 1st gen Core i5/i7 could have issues as those don't have AES-NI in hardware or sumsuch plus they're SATA2 only, but those would be 15+ years old at this point.
with btrfs that has on-the-fly compression, copy-on-write, and deduping, everything works seamlessly, even when I have database-spanking applications in local development.
so the only thing I've changed recently is encrypting every device I have, not just the mobile ones. the standalone devices get unlocked with a key-file from the local filesystem so they boot without the prompt. selling/giving away any of those drives, mechanical or SSD, is now a non-issue.
