I'm not saying that's the case with your system, but my immediate thought when I see those numbers is: how much of the value from those 4m/s writes could you get with a system that did something like 100 w/s? Either through sampling/statistical methods, reduce "write amplification" or simply looking hard at what is written and how often :-)
