ext4 on md raid1 on SATA. Nothing too complicated.

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: <none>

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.)
