Survey on Deduplication Techniques in Flash-Based Storage

Data deduplication importance is growing with the growth of data volumes. The domain of data deduplication is in active development. Recently it was influenced by appearance of Solid State Drive. This new type of disk has significant differences from random access memory and hard disk drives and is widely used now. In this paper we propose a novel taxonomy which reflects the main issues related to deduplication in Solid State Drive. We present a survey on deduplication techniques focusing on flash-based storage. We also describe several Open Source tools implementing data deduplication and briefly describe open research problems related to data deduplication in flash-based storage systems

A data compression scheme for reliable data storage in non-volatile memories

This contribution presents a data compression scheme for applications in non-volatile flash memories. The objective of the data compression algorithm is to reduce the amount of user data such that the redundancy of the error correction coding can be increased in order to improve the reliability of the data storage system. The data compression is performed on block level considering data blocks of 1 kilobyte. We present an encoder architecture that has low memory requirements and provides a fast data encoding
