Patent ID: 8370720

Claim:
A self-powered solid-state drive configured to perform offline scrubbing of solid-state mass storage media, the drive comprising: a package comprising a printed circuit board; a system interface coupled to the circuit board and adapted to connect the drive to a host system; at least one nonvolatile memory device on the circuit board; controller means on the circuit board through which data pass when being written to and read from the memory device; a volatile memory cache on the circuit board; means on the circuit board for performing the function of a real-time clock on the circuit board; a system logic device configured to operate when the drive is not functionally connected to a host system, execute copy commands without accessing a host system, and prioritize preemptive scrubbing of addresses in the memory device on the basis of risk of data loss based on one or more parameters logged by the internal system logic device; and an integrated power source on the circuit board for powering the drive.
