If somebody uses RAID 5 with SATA 300, PCIe link can transfer 250 MB/s only, what is edgewise, 8 HDDs has read around this 250 MB/s. But with two SSD, this is huge bottleneck.
With SATA 600 is the bottleneck even worse and I am afraid we need more than just two PCIe links per controller. New HDDs would have higher read and write speeds and if you'll use more of them, you would be :banana::banana::banana::banana:ed up (sorry to say, but it's true).
So we need at least two PCIe 2.0 links per every USB/SATA controller. Does the RS890 have something like that? If doesn't, there is nothing to be happy about.
