IOMeter is another open source synthetic benchmarking tool which is able to simulate the various loads placed on hard drive and solid state drive technology.
OCZ fell a little short of their claimed 4kb random/write performance of 60,000 IOPS and our results were a little lower than initially anticipated, at 58,345. ADATA have obviously tweaked the 240gb S511 drive however as it manages to score just over 60,000, which is a heck of an achievement.
