Intel IOMeter: FileServer & WebServer

Server patterns come next.

The picture tells more than words can say. WD2500JB is a bit faster than WD2000JB, while the IBM drive is much faster than both WD solutions under medium and high workloads. Maxtor lags behind the rest under any workload, so we can’t say anything good about its “server” optimization…

It’s curious, but again we see Maxtor drive performing differently with different UDMA controllers when processing 16-requests.

Let’s calculate the performance rating of the drives by averaging Total I/O values under all workloads:

We get just what we have expected to see: WD2500JB has a small advantage over WD2000JB and they both fall behind the IBM drive.

As the WebServer pattern has write requests, WD drives are deprived of their trump, the excellent lazy write implementation. So, only the most optimistic people, like myself, can expect them to notch better results. :)

I took a look at this graph and all my optimism disappeared instantly. Nevertheless, I should point out that WD2500JB is notably faster than its fellow drive in this pattern, so there is some progress to be mentioned. You can also see it in the ratings diagram:
