You can do really cool things with Linux RAID, like RAID stripe across 8 virtual (i.e., EBS @ EC2) volumes and then layer dmcrypt on top of that or other things for use cases that it was never even designed for. Linux RAID (and volume management) were really designed The UNIX Way as modular, small tools that can be applied like Lego bricks, and no where is that more user-visible than in the RAID/LVM/etc subsystems.
Now do it with multiple 1.2MB 5.25" drives if you can find a system with a BIOS old enough to support the hardware, yet new enough to run a modern kernel.
