[PERC S130] Slow performance

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.

You have my condolences, perhaps the worst raid performance I have seen... sneaker-net might be faster, as long as you walk fast....

Agree with Flash, it would be difficult to diagnose as there could be 100 variables to look at.; aside from the fact the raid controller is about as low quality  as you can go, perhaps the lowest.. You might get somewhere if you had a tech on site who has run into this controller before, but you would be better off getting a H7x0 controller as suggested. Personally I have dealt with many low end raid performance issues, it is just not worth spending an inordinate  amount of time on them.  Cut your losses, purchase a high end controller. Another thing, the low end controllers are dangerous as far as possible data loss.
