IBM much faster

Fredrik has hit the nail on the head, the response time for writes and reads is far better on the IBM. What are most businesses going to be using this kit for? Databases. What has to be performed synchronously on a database and is going to seriously hit you if the performance is poor? Every COMMIT (i.e. a save of the changes the application has made to the disk).

At every % workload figure, the NetApp fails to impress. At 10% load, the NetApp takes 2 and a half times as long as the IBM to complete that commit. By 95% load, that multiplier has leapt to over 6 times as long.

Not sure about other workloads (e.g. scientific), but for databases give me the IBM every time.
