I honestly don't think there is any sort of setup that will work as you described. If you want to have an array continue to function with missing devices, you *will* have to sacrifice some space. The closest type of block device I can think of which *might* achieve your goal is spanning. Basically it turns all four drives into one huge drive but doesn't stripe across them so *some* data will survive a device failure. Even if you were use spanning (assuming mdadm supports it, haven't looked) and md doesn't complain when the device drops out, the filesystem will choke as soon as you tried to access the data on the missing device.
