Personalities : [raid0] [raid1] md1 : active raid1 sdb2[1] sda2[0] # Root partition 41942976 blocks [2/2] [UU] md2 : active raid1 sdb3[1] sda3[0] # /home partition 100663232 blocks [2/2] [UU] md0 : active raid1 sdb1[1] sda1[0] # Swap partition 25165696 blocks [2/2] [UU] unused devices: There's 8G of RAM, and a large swap partition because I download a lot of videos to tmpfs on /tmp. (/tmp is capped at 16G, and swap is 24G, so I shouldn't run out, but there was certainly quite a few GB of stuff there.)
