4KB Random Write Steady State Performance
Here we see the worst possible random write condition. Again, the JMF670H's performance scales as capacity increases due to interleaving.
If you're striping SSDs for a performance increase, you want to see consistency in this metric. Variability multiplies with each product added to the array. If the swings are large enough, you might as well roll a dice to see if you're getting a fast write or a slow one for each request. The three JMF670H-based drives we tested do a good job of minimizing fluctuations, while keeping the lowest write condition high.
