Abstract

Recent SSDs use parallel architectures with multi-channel and multi-way, and manages multiple pages in a group, called superpage, to reduce the size of address mapping information. Such a coarse grained mapping provides a poor performance for small sized random write requests. To solve the problem, this paper proposes a novel host-level device driver, called HARD, which merges several small sized random write requests into a long sequential write requests. Experimental results showed the proposed HARD improved the random write performance by up to eight times.
