Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: A Flash Translation Layer (FTL) provides a block device interface on top of flash memory to support existing disk based file systems. Due to the erase-before-write feature of flash memory, an FTL usually performs out-of-place updates and uses a garbage collection procedure to reclaim stale data. Superblock FTL is one of the ll-known FTLs, which achieves good performance in terms of both garbage collection overhead and RAM usage. The use of fine-grained mapping information allows a logical page within a superblock, i.e., a set of contiguous logical blocks, to be placed at any page offset of the physical blocks allocated for that superblock. In addition, the fine-grained mapping information is stored in the spare area of NAND flash memory to reduce the RAM usage. Generally, the FTL performance improves with larger superblocks. Hover, the spare area management approach of the FTL prevents it from supporting large superblocks. ,  propose an FTL that incorporates a novel spare area management approach to enable the support of large superblocks. The simulation results from four traces show that the proposed FTL reduces the garbage collection overhead by up to 89%, when compared to the Superblock FTL. In addition, it results in shorter response time.
