RAID question


May 4, 2012
My new m17xr4 has 2 500gb wd blacks in it right now.
I want to add a 64gb msata cache drive and a 1tb drive to the odd.

Now here comes the question.

I want to raid the 2 500s together for faster performance, then cache it with the msata. Then add the 1tb to the odd and riad that to the pair of 500s as a mirror of the 500s...

So short version.

Raid 500s to make a 1tb, then raid the 1tb to another 1tb leaving me with a total of 1tb of space on 4 hdds :)
