i have come across this[1] wiki page, and realized i should use softraid
with my setup.  i never realized these built-in controllers were "fake"
RAIDs.  sketchy manufacturers... ;-)

so, i searched around, and followed the instructions at [2], up to
creating the first array.  now i have /dev/md0.

then, i jumped over to [3], since i want it to be encrypted, and started
with step 1b, filling the device with random data.  that is still
running, and will take about 4 days by my calculations to complete.
then i will continue with that guide.

in the meantime, if anyone has any tips, etc. i would appreciate it!

thanks
