    Hi, I'm new to the MacRumors forums. Great info being shared here thx. My question is concerns purchasing a PCIe card with a built in SSD and if that would be faster (speed-wise) than adding an SSD in the drive bay which would be limited to the slower 1.5Gb/sec limitation on PPC Macs. Thx

    Ok sure it is DC, it's too bad that it won't boot from it. Thx for the info.

    Can you actually boot from sata 3 cards in the pcie powermacs?

    I'm not sure that's why I'm asking. I assume since it is direct to the motherboard it would be faster than a sata connection, but you know what happens when you "assume."

    of course a pcie ssd is faster than a sata connection , but i was wondering if there was an alternative to a pcie ssd since the pcie ssd suggested in this post is not bootable. I was wanting to find out if there is an alternative for the faster connection of a bootdrive in a powermac.

    Some PCIe SATA cards are bootable, but the only driver available on the PM G5 is 1.5 GB/s, so a SATA II/III card will not be faster. (From what I remember being told)

    Nope. The limit is PCIe bus (1.0, 2.5 GT/s) and lane width of the PCIe card.

    It appears I have beaten the already dead horse, probably bones by now.
    Thanks for all your input everyone.

    But you can boot from SSD connected to PCIe SATA III card on ASM1061 chipset. It would max about 250MB/s, because it's PCIe x1 and G5 has PCIe Rev 1.0 slots. It's always 100MB/s more than internal SATA.

    Thx, but is a 100mb/s worth the cost? Maybe if I could find it used with the correct chipset.
