Hardware choice for industrial nodered

No, I'm afraid you don't. That was the point of my previous comments and here: [Reference] Optimising Node-RED - #5 by TotallyInformation.

It is certainly true that what you say will lighten the load on the card and make it easier to last longer.

However, this is certainly not required. A decent card is certainly capable of lasting years with at least moderate use. My own cards have lasted a long time (years) with no special care at all. Albeit that they are getting what I would call moderate use - they consistently see 1-2 writes per second 24hrs a day. Last time I had to replace a card was in 2015. That was when I moved to larger cards of better quality - not had a failure since then.
