You must use a controller if using a backplane - you cannot plug the backplane into the onboard SATA ports. You would need to find a way to adapt the power to provide for the drives. With your setup, I would replace the PERC 6 with an H200 and run the drives "unconfigured" (non-RAID), to essentially pass them through as individual drives.
Hi   My home server is T410, I want to replace the 2x 1TB HDD with SSDs I am interested in model:  [URL]   However, this is a 1TB SSD, and it is desktop model, will it work on my server?   and if I dont want to achieve RAID, do still I need to buy RAID Controller to connect these disks into my motherboard?   the RAID Controller currently is PERC6i, and I believe it is 3Gb/s while the SSD disks I want are 6Gb/s     thanks,  
Can I used normal SSDs in Dell T410
