I am surprised someone hasn't come out with an add-on card that does hardware Kraken yet. I suppose there will be a licensing issue though.
Sounds slightly different as Fabian says it's different from what you get in an off-the-shelf SSD.
He said I/O coprocessor exists too in off the shelf SSD but the change is a custom firmware very different of off the shelf SSD. From the patent it seems the controller is customized a bit to be better at reading data.
