I simply popped out the SSD and I have no problems - hashing away, never stopping. The burden of hosting a node does absolutely nothing for me - no benefit at all. Just happily mining SHA-256 crypto, stuffing my wallet!
I removed my ssd too as I already run full BTC and LND wallets/nodes via RASPIBLITZ on an 8 gig Pi 4.
My controller and two slaves have been working like trojans on 'balanced mode' for weeks with no problems.
