8/19    Anyone have a good MLC vs. SLC writeup that is less than a year
        old? I am investigating making a big SSD order. -ausman
        \_ how much performance gain are you expecting from using SSD?
           Let's say your 7200RPM yields 70 MB/sec (sustained) read and
           your new SSD yields 160 MB/sec read, and that your application
           is mostly streaming media (so the platter is continuous read,
           mostly). Do you expect a 2X performance? Now, let's say your
           application is mostly short random meta-data reads and your
           7200RPM now only yields 32MB/sec read, while your SSD still
           yields 160MB/sec read. Do you expect a 5X performance in your
           response time or throughput, or both? I'm quizzing your ability
           to perform calculations as an architect.
