Haven't finished all the tests, but first results tell me the Acard is a tad faster than 3x-iRam (in PCMark). The Acard is imho easier to use as you don't need any PCI lanes and you can have a Raid 0 configuration without having to buy two. In addition, there's a direct backup function available and it's possible to have a larger harddisk (upto 64GB iirc).


It's quite expensive, though.
