A system for and method of providing a flexible means of using and storing file configuration metadata in a RAID network, so that the memory system does not restrict the metadata to exact format or location in memory. A RAID controller is operable to power-up a memory device, to determine whether the memory device is new and, if so, to build and configure a file system on the memory device. Configuration data is communicated to the RAID controller. If a configuration update is needed, the RAID controller updates the configuration file of the memory device.
