Abstract
Mechanisms for storing data to a storage system comprising a set of one or more solid state storage devices and a set of non-solid state storage devices are provided. A request to write data to the storage system is received and the data is written to the set of one or more solid state storage devices in response to receiving the request. Moreover, a mirror copy of the data is written to the set of non-solid state storage devices in response to receiving the request. Thus, the non-solid state storage devices serve as a mirror backup copy of the data stored to the solid state storage devices.
