Advil: A Pain Reliever for the Storage Performance of Mobile Devices

Je-Min Kim, Jin-Soo Kim
2012 2012 IEEE 15th International Conference on Computational Science and Engineering  
Advil filters out small random writes and logs them sequentially into a small buffer space (called reserved area), in a transparent way to file systems and flash-based storage devices.  ...  The poor random write performance is particularly painful to mobile devices, but this situation is expected to continue due to limited cost and power budget in embedded flash-based storage.  ...  Using a flash-aware file system is not an option either.  ...

Weon-Il Chung, Liangbo Li
2010 International Journal of Contents  
This paper proposes a memory compaction scheme based on block-level buffer for flash memory.  ...  The proposed scheme not only merges the data blocks and the corresponding log block, but also searches for the block-level buffer to find the corresponding buffer blocks.  ...  For the buffer management policies which manage blocks with hot and cold blocks, we need not divide the buffer to two partitions.
