Most commodity flash disks exhibit very poor performance when presented with moderate-sized writes that are not sequentially ordered. We argue that performance can be drastically improved through the addition of sufficient RAM to hold data structures describing a fine-grain mapping between disk logical blocks and physical flash addresses. We present a design that accomplishes this.
