The controllers themselves really aren't that interesting any more - an SSD controller is really just an ARM or MIPS core with some flash interfaces, a SATA interface, and some ram - running proprietary firmware. Several of the Marvell devices actually have completely different firmwares (e.g. Intel's firmware for Marvell devices was reportedly developed by them in-house), and Intel's Sandforce firmware has some customizations for improved reliability, at the expense of some speed. -- Calvin Walton
