I must say it seams to be performing preatty poorly.. I am not sure how much cache is in the controller. I will investigate.

I had posted similar numbers a while back on a DS3300. Wasn't very impressive.

My response times were similar to yours christianZ, but with IO under 500 with the "reallife" test. Of course, I was testing with only 3 drives at the time. I posted non-ESX (physical hardware) specs against the DS3300 and they were consistent with the VM results.

Since this thread is getting longer and longer, not to mention the load times, Christian and I decided to close this thread and start a new one.

The new thread is available here: New !! Open unofficial storage performance thread
