Hard to troubleshoot, because it is hard to know what proper expectations for these controllers should be. Begin with the starting point that these S130 controllers are pretty horrible. They are rebranded Intel chipset RAID controllers, which is bad enough, then they have a Dell branding layer thrown over them, making them even worse.  My recommendation is that if you ever even CONSIDER running a benchmark, do not use these controllers. You would be MUCH better off with OS-managed RAID if you care about performance with no investment in decent hardware.  In nearly all scenarios, the H7x0 controllers should be used.
Server: PE R230 OS: Windows 2012 R2 RAID: 1 Driver version of raid controller: 4.2.0-0009 [IMAGE] [IMAGE] Performance of i/o operations is very slow. Any idea what can be done to increase it? 4.2.0-0009
