What is the actual maximum number of items that can go in the TR Cache?

There's been a number of extra bag slots and bank slots added to the game in the 5 years I've been playing.
I have 8 Bag Slots {160 items} + what I'm actually wearing and 5 Bank Slots {another 100 Slots}.

As much as I can before TRing I've been emptying my Character Bank into my inventory - Is this just Paranoia or do we now have more slots than the TR Cache can cope with?
