The only difference with these products is that the raid chip is on the card rather than the mobo. The Revo Drive/ IBIS drive use Silicon Image raid chips. SiI3124 & 3124.

In that context you are not decreasing your risk you are increasing it because it then goes to a PCIe interface.

You can’t TRIM the drives and I don’t think it is possible to update the firmware unless you send the drive back to the manufacturer. There is no built in power backup facility and the power back up capacitor used on the more expensive SF1500 drives has been omitted.

The design of these products suggests only one thing. They are for the enthusiast that does not mind rebuilding his array when it fails.
