Generally I buy drives at the sweet spot in cost/capacity, so that is
about 3TB last time I checked (for spinning disks).
I ALWAYS use RAID or full backups of some kind. RAID isn't really a
substitute for backups, but I use it as such for low-priority data
such as mythtv recordings or re-generatable data. Right now I'm
running on mirrored btrfs with a full backup to ext4 (since btrfs is
living dangerously). I'm actually getting tight on space and debating
dropping the full backups for lower-priority data, which would free up
a 3TB drive to add to the btrfs array. Long-term I'd prefer to move
to raid5 which is much more efficient, but I wouldn't recommend doing
that on btrfs yet - it is very immature.
raid5 on mdadm and lvm with ext4 is very mature, and is probably your
most space-efficient option with some level of redundancy. With large
arrays having raid6 isn't a bad idea these days - it takes a lot of
time to recover a failure. However, if you have a single drive today
there is no way to add only a single disk and get both more space and
redundancy at the same time. If you want more space and only want to
buy one drive, then you're stuck with just simple lvm and if a drive
fails you're going to lose a lot of stuff.
