i dont have 400 gb tables on SSD. 3x table around 300gb 00,ff,03 Raided to 1tb. If i was building tables today then i would opt for over kill. My tables are ancient. Today storage is cheap. checked on rbt v2 FF also and not found. Someone elses v1 table may have better luck
ideally i would say 400gb is good for v1 although it was stated around 250gb was sufficient for 95%+. Chains can contain errors though. When rbt adds the chains it does minimal checks for validity
probably need to run a larger sample size rather than 20.. not checked the ssd's for errors, they are 13+(unlucky for some) years old. from back when Colibri started the project
