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. |
