US Patent 11892916 Dynamic fail-safe redundancy in aggregated and virtualized solid state drives

A solid state drive having a drive aggregator and a plurality of component solid state drive, including a first component solid state drive and a second component solid state drive. The drive aggregator has at least one host interface, and a plurality of drive interfaces connected to the plurality of component solid state drives. The drive aggregator is configured to generate, in the second solid state drive, a copy of a dataset that is stored in the first component solid state drive. In response to a failure of the first component solid state drive, the drive aggregator is configured to substitute a function of the first component solid state drive with respect to the dataset with a corresponding function of the second component solid state drive, based on the copy of the dataset generated in the second component solid state drive.
