Below are screen shots of how ASRock implemented this chip and how I configured it in RAID.
The BIOS of the ASRock motherboard is P1.10.
I take it the configuration utility in my screen shots is HBA and not WebBIOS?
I noticed under the MegaRAID utility it doesn't allow me to change the write policy and keeps it write-through. Is there a way to force that to write back? (I have a UPS for the computer, but the motherboard LSI chip does not have a battery backup). I only have one option (Disk Cache Policy) and not all of the options as found here:
How to enable write back cache (write cache) on MegaRAID controllers.
Under MegaRAID my settings are: Access Policy- Read/Write, Disk Cache Policy- Enabled (only settings I can change), Read Policy- No read ahead, IO Policy- Direct IO, Write Policy- Write Through.
Also, in the BIOS configuration utility there is absolutely nowhere to change the stripe size during volume create. Is this on purpose? It only uses the default 64kb. Some say that my low performance may be because I am not using 128kb stripe, but I highly doubt that as 64kb has done really well in mixed-use scenarios in recent RAID tests versus other stripe sizes.
