SOLO>POOL if you have 5TB or more.
I have about 7TB but not in one peace, just divide for some rigs. I have to stay in pool :/
That's not how mining works, you storage does not have to be in one rig. As long as the nonces don't overlap, you could have 100TB spread across 200 rigs and it would be the same as having them all on one rig.
When you get a winning share for a block, it only comes from one of your plot ranges, not a combination of the whole.
Give solo mining a try for a day or two, you'll be happy you did. Not getting antsy is the key, set it and forget it and watch the blocks come in.
