Systems, apparatuses and methods may provide for technology that digitally signs a hash table and a data payload, wherein the data payload is partitioned into a plurality of storage blocks and the hash table specifies how to index into and individually authenticate the plurality of storage blocks. Additionally, a write of the digitally signed hash table and data payload may be initiated to an aggregate storage array. In one example, the aggregate storage array authenticates the digital signature of the hash table and the data payload and conducts a write of the data payload to a plurality of drives in the aggregate storage array in accordance with the hash table.
