    That's because HDD's aren't quick enough to hit SATA III anyways. I'm sure that the R4 has all SATA III.

    I meant the physical bays, I guess I should have omitted the HDD reference.

    HDD 0 and 1 are both SATA III, the MSATA is SATAII. But you can only use SATA II slot with an MSATA drive and the SATA III .drives with SSD's if you want to utilize the increased throughput. From what I understand.

    Yes, main drive bays are SATA III compatible. That first document, purporting to show the differences between the R3 and R4, is often misleading, incomplete or incorrect. Hard to believe that document made it through whatever editing and quality control process applies.

    This is what I thought too until I read the two posted documents.

    Ok, I'll dismiss the first document.

    Thanks

    Just thought I'd chip in - yes the two drive bays are SATA III, but the mSATA slot is advertised SATA III by Dell, but whoever seems to have tried it says its running at SATA II. Doesn't make much of a difference really but still... maybe a BIOS update will rectify that? Idk. HP for example disabled SATA III support from their f.22 BIOS onwards, which is why I flashed back to f.20. Oh the stupid things they do...

    NP, running a 3 disk raid 0 array has no downsides that one disk is sata 2, see same thread for benchmarks.
    you will get max write speed with triple m4's and read will stop at around 800 mb/s
