OK the system is now up and running. I configured a RAID 5 array of four Seagate ST3000DM001 hard disks.
I installed the RST driver and was able to access the RAID volume. One thing still bothers me: While read speed is awesome (>430 MB/s) the write performance is very low (~30 MB/s) and I did not manage to enable write-back caching for the volume. The RST help says that i just have to click on "enable" in the management options of the volume but the RST GUI does not show the appropriate button. Could you also help me with this issue please?
