My laptop is my workstation, it's running almost 24/7 on SSD with btrfs. The main thing is having a good SSD (right now Samsung 840 EVO 1TB for me).

Again, you really want to avoid the LVM layer. It will only make things slower. This is my drive with encrypted swap Device Boot Start End Blocks Id System /dev/sda1 * 2048 1050623 524288 83 Linux /dev/sda2 1050624 42993663 20971520 83 Linux /dev/sda3 105908224 139462655 16777216 82 Linux swap / Solaris /dev/sda4 139462656 1953525167 907031256 83 Linux See https://btrfs.wiki.kernel.org/index.php/SysadminGuide#btrfs_on_top_of_dmcrypt and solutions like https://github.com/gebi/keyctl_keyscript > All my machines have been made this way for *years*, so I know it works damn > well ;-) I've used LVM for years too, it makes things slower and less reliable.
