An Angelbird AtomX 500GB SSD which we use with our Atomos Shogun Inferno and Sumo 19" Monitor/Recorders. The only odd thing about these is that even though they're listed as compatible with the Atomos products, they don't fit into the caddy's and therefore get buried in the Sumo card slot. But nothing a little gaff tape pull-tab can't fix, am I right?
