Introduction
Redundant arrays of independent disks, or RAID, systems by nature are designed to preserve data in the face of adverse circumstances. One example is power failure, thereby threatening data that is temporarily stored in volatile memory. To protect this data, many systems incorporate a battery-based power backup that supplies short-term power—enough watt-seconds for the RAID controller to write volatile data to nonvolatile memory. However, advances in flash memory ...
