AnandTech Storage Bench 2011, Light Workload

Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric). The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:

Light Workload 2011—Average Data Rate

As our Light Storage Suite is more small IO centric than our Heavy suite, the difference between the Performance Pro and Plextor M3 is only 2MB/s now, which is essentially nothing.

    What about write amplification and the longevity of the drive? I thought that would be a hot topic given the aggressive garbage collection! AT is about the only site where such a thing would even be addressed, so I'm sorry there's no discussion here.
