Abstract
The present disclosure relates to utilizing a storage system that improves memory storage and access by utilizing a distributed erasure coding RAID. For example, the storage system stores a mapping table within volatile memory of one or more SSDs on a set of RAID SSDs. In particular, a mapping table stored in one SSD in the SSD set includes mapping information corresponding to data stored in another SSD in the SSD set. In this manner, the storage system can significantly reduce the number of operations needed to write new data to the set of SSDs from previous methods that required multiple reads and multiple writes.
