Fair warning: It is very dangerous to make statements like this in a public forum like this.

You run the risk of someone spotting it and making a seemingly-innocent reply along the lines of, "Oh, you should at LEAST have TWO disks set up as a mirror so you don't lose all your movies when (not if, but when) the disk dies." And then someone else will say, "LOL u noob, RAID not a backup!" Another participant will assure you that no data is safe unless it's stored at on at least a 5-disk ZFS array. And then someone else will jump in to point out that even ZFS is not safe if you're not running ECC memory. And course you can't just have ONE of these ECC-enabled 5-disk ZFS-breathing monsters, because every component ASIDE from the disks is a single point of failure, so you'd better have TWO just to be safe. Which means you'll need a UPS because sudden power loses are _awesome_ if you like having your platters scribbled all over by a browned-out disk controller. And what exactly is your disaster recovery plan in the event of a fire or flood, gotta have some infra running in good health off-site in case something like that happens. And so on.

Of course if you dig far enough into these admonitions and suggestions, the good news is that you won't have the time to watch any of those movies.
