few other additions here and ive sorted by speed
as we can see the best technologies for mac os 9 i will bold;)

ISA 8-bit      2.39 MB/s
ISA 16-Bit      8.33 MB/s
100BASE-T         12.5 mb/s
ATA-33: 33MB/s *** (powermac g3/g4 yikes disk interface)
EISA 32bit          33.32 MB/s
NuBus 10 MHz   40 MB/s
FW400      50 MB/s *** (real world: 33 MB/s)
USB2.0 60 MB/s  *** (real world: 25MB/s)
ATA-66 : 66MB/s *** (most powermac g4 disk interface)
32bit CardBus 1   66.66 MB/s
NuBus90 20 MHz   80 MB/s
FW800 80 MB/s ***  (real world: 45MB/s)
ATA-100: 100MB/s ***
gigabit ethernet   125 MB/s
32bit CardBus 2   133.33 MB/s
PCI 32bit/33MHz   133.33 MB/s  (in most pcs + most short pci cards for mac)
ATA-133: 133MB/s ***
SATA150 150MB/s *** (real world burst:115MB/sec ... sustained: 58 MB/sec )
PCI 32bit/66MHz   266.7 MB/s
PCI 64bit/33MHz   266.7 MB/s (most mac pci slots)
AGP 1×           266.7 MB/s
SATA300 (sata2) 300 MB/s ***
AGP 2×           533.3 MB/s (sawtooth/gigabit)
PCI 64bit/66MHz   533 MB/s
SATA600 (sata3) 600 MB/s ***
USB3.0 600 MB/s ***
PCI 64bit/100MHz   800 MB/s
AGP 4×            1.067 GB/s (digital Audio / Quicksilver  / MDD)
PCI-X 133       1.067 GB/s
thunderbolt 1.250 GB/s ***
PCIE 1.0 (×8)     2 GB/s
PCIE 2.0 (×4)     2 GB/s
AGP 8x      2.133 GB/s
PCIE 1.0 (×16)    4 GB/s
PCIE 2.0 (×8)     4 GB/s
PCIE 2.0 (×16)    8 GB/s
PCIE 3.0 (×16)    15.75 GB/s

so u can get better performance using a network fileserver then u can with a firewire drive (use your rotational drives here?)
but the best transfer speed will be sata/esata 150 (best used with SSD) which kicks the crap out of FW400 or FW800
but this is not TOO TOO much better then using ATA100/ATA133 (addon card) with SSD (ide ssd or via sata converter)
(aga133 vs sata150 isnt much different, real benefit is ssd access times + fast writing flash ram)

ATA66 is very much worth spending $$ on upgrading to ATA133 and using a pci slot - especially at low cost of ata133 pci cards
(ata66 is in every powermac g4 practically, so this means sawtooth,gigabit,digital audio, quicksilver models -  the mdd adds 1xATA100 but still has 1xATA66 port - make sure u are running your os drive off ata100+ speed connection port) but this mostly applies worst of all to the G3 powermac + yikes g4, which have only ATA-33 speed disk interface.. the worst of all - so adding ata133 or sata150 is a HUGE improvement!!!!!! for these pci graphics macs to jump from 33 to 133+

we can also see that lacking of gigabit ethernet is the biggest handicap (ie: 10-base t network speed SUCKS!)
so everyone with a pre-gigabit ethernet mac should 100% invest in a gigabit ethernet pci card

this article helped me - i have 2 of these cards and they work well under mac os 9
im sure there are other cards if anyone knows of one please share that info!

http://www.everymac.com/ultimate-mac-sort/ can be handy when looking up these facts

supernova777:
another thing i see here is the similarities between PCI-X + AGP

PCI 64bit/33MHz == agp 1x

pci-x 66 == agp 2x,

pci-x 133 == AGP 4x

pci-x 266 == AGP 8x

which makes me think AGP doesnt even really exist..
but this is just a renamed PCI-X slot for graphics purposes;)
because they are exactly the same bandwidth wise
they are parallel in bandwidth these technologies

supernova777:
according to this chart gigabit ethernet is faster then fw400 by a great deal..

it was briefly brought up by protoolsleguy ..
maybe it needs more thought?
could recording to a network drive be dependable?

Probably if you use a more stable protocol. Like iSCSI. Hence my question in the other thread ;)

Yes it is. But there is something weird about this...
Gigabit ethernet (1000 mbits/sec) should be 60% faster than FW 400 (400 mbits/sec). But accordingly to my tests with file transfers, it is just 20% faster than FW 400...
