    Hey this might be an insanely dumb idea, but I just bought and installed this:

    StarTech.com 2 Port PCI Express SATA 6 Gbps eSATA Controller Card

    In addition to the 2 eSATA out the back, it has 2 SATA ports inside. I'm guessing I can plug something like a Samsung 850 PRO into this, but is there any advantage to this versus the intended mounting with the drive slots? Speed boost at least? As for the downfalls, I bet this would not be a bootable solution.

    Thoughts?

    since the internal S-ATA ports are 3 Gb/Sec only you would get twice the speed (approx 500 MB/Sec instead of only 250 MB/Sec).

    Oh good, I'm not completely off the mark. So that just leaves the bootability question...

    I did see this, however I needed eSATA ports (to stretch the life on my old gRaid drives). Great suggestion though! I've been looking at the other PCIe card that thats the blade ssds, but even that I put a pin in to wait for the SSBUX drives to stabilize in price.

    Looks like Asmedia chip, don't buy it if it is. This one is PCIe x1 and it will be maxed out ~350MB/s.

    Anything on Marvell 9230 with PCIe x2. Max throughput ~750 MB/s.
