I have been using the onboard SATA connections on my Supermicro H8DGU motherboard.  And have 3 10TB drives (1 Parity, 2 data) with a 240GB SSD cache.  Under heavy load, the system disk subsystem bogs down (mover running, handbrake conversion, uploading large video content).  I have a 10Gb Fiber connection that is not even coming close to saturation between my desktop and Unraid server. 

 

So I am looking to slap an HBA into the box and open the pipe as it were to increase my disk subsystem io.  I know I will need to flash whatever LSI type of HBA to IT mode.  But once I have installed the hba, will I need to do anything else.  I am not adding any devices, just changing the data path.  Of course a back up will be taken of the data drives.

What throughput are you getting now? That small of a pool will probably not benefit from moving to an HBA

I am topping out at about 150MB/s.  The main reason is the sata ports are sata I topping out 150 rate.  The drives are WDC 10TB Red and a 240GB SSD
