As access times to main memory and disks continue to diverge, faster non-volatile storage technologies become more attractive for speeding up data analysis applications. NAND flash is one such promising substitute for disks. Flash offers faster random reads than disk, consumes less power than disk, and is cheaper than DRAM. In this paper, we investigate alternative data layouts and join algorithms suited for systems that use flash drives as the non-volatile store.
