The server is X3650 M2 with dual quad-core CPUs, 20GB memory, and 4 10k SAS drives in RAID 10 running Win2008 64bit on a IBM ServeRAID M1015 SAS RAID Controller.
I did a Bart's Stuff Test. The hard drive only runs 35MB/s!!!??? Any of my home computers runs faster than that!!!
What could be wrong? The only thing I can think of is that when I installed the RAID controller, I took out the old onboard LSI RAID card and put the controller in that spot.
