I'm not familiar with your specific systems, but generally speaking...
RODI units create water at the rate of more or less their GPD rate. For example, a 35GPD RODI unit will produce water at a rate of 35 gallons per day under nominal conditions (water pressure, water quality, etc).
As mentioned, this rate varies according to how bad or good your water is to start with, your water pressure (60psi is pretty normal and what most people have give or take), and the age/wear on your cartridges.
It's not like you can place a bucket under it, open a valve and fill it; the water trickles out very slowly. Most people use some sort of storage reservoir. I use a 32 gallon Rubbermaid Brute trash barrel with a bulkhead on the bottom and a valve. The unit trickles water into it, and a float switch at the top turns it off when it is full.
Remember to get a unit rated for the maximum amount of water you see yourself using. Bigger units may seem like a way to avoid the reservoir, but they are not, and their cartridges are really expensive to replace.
