Exploiting subnets, you can store ridiculous amounts using a single channel. This relies on an ME interface, and a storage bus. Essentia doesn't work with either of the above, so if your drive containing all your Essentia storage disks is in one of the aforementioned subnets, it won't be available to the thaumic devices on the network.

Hmm, intriguing idea. I will look into adding something similar via the essentia provider.
On your main network you would have an essentia storage bus, on your sub-network a ME Interface.

Edit: Subnets now use the ME Interface.

yay +1 for this one :)
