Abstract: n this paper we build on our research in data management on native Flash storage. In particular we demonstrate the advantages of the intelligent data placement strategies. To effectively manage the physical Flash space and organize the data on it we utilize the novel storage structures such as regions and groups. These are coupled to common DBMS logical structures, thus introducing negligible extra overhead for the DBA. The experimental results indicate an improvement of transactional throughput for OLTP benchmarks of up to 60% and decrease in write-amplification of up to 2x, which further doubles the longevity of Flash SSD.
