PMG5 2.3DP PCIe card with built in SSD

Sonnet Tempo SSD is listed as compatible with G5, but non-bootable:

P.S. If PCIe, it would be 2.3 DC, not DP

 

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

 

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.

 

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.

 

It's about 10-15 bucks, so judge yourself
