exploring 66mhz pci-slot on non-agp *pci* mac g3 450mhz!!!!

Protools5LEGuy:
G3s are 8.5.x 8.6 MacOS machines.
A G3 is as fast as a G4 with non ativec-optimized apps in a clock by clock basis. Finder is one "G3 coded" one

So the dream of having 266mb/s for cheap on the g3 is put to rest;(

You can still put 3 cheaps cards and make a Raid with 3 / 6 drives even if they work at 33Mhz only.

No. If the card and the PCI Bus can't go at 66 Mhz and/or 64 bits, the 133 MB/s barrier can't be surpassed. No matter how many RAID you put on the PCI bus. In fact, just a single SSD on a ATA-133 or SATA 150 can saturate the 33Mhz/32bits PCI bus.
That's what I've done with 64 bits card,  and chrisNova777 is trying to do with 66Mhz.

Jakl:
By the way Chris what sata card/cards did you try to use?
Were any of them Seritek cards?

Thanks

I guess in a magma 64bit chassis with 7 slots, 7 cards should give 133MB/s.

I guess even a 32 bit should do if the processor is fast enought to handle the I/O of hard disks.

I said to use various cards for the raid to saturate a little less every sata controller from every card.
