    I have a Mac Pro with Mavericks installed on the SSD mounted on the Velocity.

    I also have Snow Leopard on one of the internal hard drives.

    Mac Pro wants to boot into SL despite me setting 10.9 as the boot drive.

    If I boot and hold down option key I can quickly and easily select the SSD with Mavericks installed.

    When I was running 10.8 it would pick the SSD but only after having a bit of a think - almost as though it was hunting through the drives to find one which had been "blessed".

    Ideas? Switch the slot the Apricorn Velocity is in? Clean install of Mav?

    Hmmm, I don't have that Issue. What SSD are you using (brand and size)? I have Lion, ML, and Mavericks on internal HDDs and I boot from my Samsung SSD/Apricorn Solo x2 combo with no issues. My Solo x2 is mounted in PCIe slot 3.

    Edit: Sorry, didn't read the title:eek: What slot is the Solo x2 mounted in? In the 3,1 Mac Pro, Slots 3 and 4 (the 2 top slots) are PCIe spec. 1 slots, Slots 1 & 2 (the 16 lane slots) are PCIe spec 2 slots. To get maximum performance from a 3,1, the Solo x2 needs to be mounted in slot 2.

    I think its an OWC 128GB SSD. Not sure which slot - will check.

    Slot 1 - Radeon 5770 (upgraded from stock card it came with)
    Slot 2- Caldigit USB 3 adapter
    Slot 3 - empty
    Slot 4 - AHCI Controller (being the Velocity Solo Card)

    ^^^^As stated in my post above, on a Mac Pro 3,1 the Solo x2 needs to be in slot No. 2. Your Caldigit Card also requires a PCIe 2.0 slot to run USB3, so you appear to have a conundrum my friend.

    However, FYI, the slots in a 4,1 or 5,1 Mac Pro are all PCIe 2.0 spec.

    So I will drop the USB 3 card and move the Velocity to see if that works.

    @flowrider,; I don't understand why you say the CalDigit USB3 card needs PCIe ver. 2.0?

    According to MacSales it runs fine (for USB3) in PCIe ver. 1.0/1.0a. Only for the eSATA/USB3 combo is it performance hampering if the card is not in a PCIe ver. 2,0 slot.

    However, USB3 does not utilise the PCIe ver. 2.0 capabilities, and runs fine on ver. 1.0! I have the combo card in the topmost slot on my Mac Pro 3,1, and it is plenty fast...

    As in how fast? I have the same card and seems to give decent speeds for me with either eSATA or USB3....would love to get closer to the max either of these interfaces can provide.

    Also, I get my Lexar USB3 card reader today, hopefully it plays nice as I have heard people having issues with it.

    Solo X2 has to go in slot 2 of the 3,1. I had to sacrifice my esata card to get the solo to work properly in mine.

    The caldigit I would swap out for a USB only fresco chipset like the Orico or Inateck cards which have driver support built in and work happily in slot 3/4 of a 3,1. esata you could always use the spare port of the Solo X2 to a PCI blanking plate.
