Why could running a Kaspa Testnet 11 node require close to 1TB of storage?

In Kaspa's Testnet 11, worst-case storage within the pruning period can approach 775 GB — nearly 1TB — because of how payload data, block speed, and block mass limits combine. Testnet 11 runs at 10 blocks per second, and payload bytes are charged at one gram per byte, with each block capped at 500,000 grams of mass. If every block were filled to that limit with payload data, the total storage across the pruning depth and finality depth (over 1.5 million blocks) would reach roughly 775 GB. For anyone wanting to run a Kaspa node, this matters because it sets a real lower bound on the disk space your machine needs to stay fully in sync with the network.
