I think ONBOARD ata-66 with a "classic" ata 3.5" 7200 rpm with 8 mb cache can give sustained 24 tracks and keep a free pci...
I could be wrong.
I don´t force PT in OS9 to work more than 8/17 tracks (Audio Click).
Be there demo from protools LE runs even on a 5400 rpm drive.
which machien are you talking about with this no pci card theory?
honestly i think your thinking is REALLY backwards on this... !
WHICH machine are u talking about having audio problems at 8 tracks?
this could be related to RAM (see my post recently about having ram sticks that are from different manufacturers)
could be related to using a disk that has poor performance
i would say its a combination of both of those things...
but usually MOST OF MY problems with computers have alwayst been related to poor disks
hard drives in general i dotn trust ..thats why its important for me to have SATA
so i can buy a new drive and replace if i need t
in my area a brand new 80gb drive can be bought at the store for 15$ now
brand new SATA2 (maybe even sata3?)
try a brand new SATA2/3 hard drive + clean matched ram
on any machine i think this would fix problems such as that.. dont try to leave the pci bus empty.. that makes no sense??
by the same logic u might aswell leave hte machine powered off and dont use the Power supply
lol
I did not test enought my Audiophile 24/96 on OS9, but 4 audio streams at 24bits @96kHz is just same as 8 audio streams 24bits@48kHz.
I guess with this Seritek 1eVE2+2 you can make a HUGE sampler and take the machine to a higher ground. Congratz Mactron!
u wait untill i post tests of SSD Raid 0 on my ACARD 6890M card.. which is only 32bit PCI and we will see if it is
indeed limited to 133mb/s as mactron has theorized.. i have a hunch this is incorrect and that this card will outperform this limitation.. but.. he may be right.. or he may not be;) we will see shortly when i try this with 2 ssd..
perhaps i will even buy the same brand + model of SSD that he did to make it a proper fair test.

http://www.macway.com/images/products_new/CAR/ACA/CARACA0001/CARACA0001_zoom_MW_0.jpgthese 32bit pci sata cards promise 1.5Gbit/s *PER PORT*
so that means using both ports in raid0 = 300MB/s
but that is top potential theoretical i think
but let me pause to review some facts:
SATA revision 1.0 - 1.5 Gbit/s - 150 MB/s
SATA revision 2.0 - 3.0 Gbit/s - 300 MB/s
SATA revision 3.0 - 6.0 Gbit/s - 600 MB/s

Conventional PCI buses operate with the following bandwidths:
PCI 32-bit, 33 MHz: 1067 Mbit/s or 133.33 MB/s
PCI 32-bit, 66 MHz: 266 MB/s
PCI 64-bit, 33 MHz: 266 MB/s PCI 64-bit, 66 MHz: 533 MB/s
this page talks about a pci-x v2.0 spec that actually added support for PCI-X
In 2003, the PCI SIG ratified PCI-X 2.0. It adds 266-MHz and 533-MHz variants, yielding roughly 2,132 MB/s and 4,266 MB/s throughput, respectively. ---http://en.wikipedia.org/wiki/PCI-X
but it appears that the world skipped this pci-x v2.0 and went straight to pci-express, so it seems they basically took this technology + shrunk it down to have a smaller connector + called it pci-e express
According to
http://en.wikipedia.org/wiki/List_of_device_bandwidths#Computer_buses SATA (SATA-150): 150 MB/s
SATA (SATA-300): 300 MB/s
Fast Ethernet (100base-X): 11.6 MB/s
Gig-E (1000base-X): 125 MB/s
and remember this image:
as u can see we are really talking about
32 bit card (my acard 6890m)
vs
64 bit card (mactrons firmtek)
but mactron is thinking that my 32bit card is limited to 33mhz which isnt the case
as u can see:
PCI 32-bit, 66 MHz: 266 MB/s
the top speed for 32 bit card is actually 266mb/s in 66mhz mode(thats why they promise 1.5gb/s per port but in reality this would be closer 133mb/s per port if both ports being used at the same time nad thats why u will never see a sata2 3g/s 32bit pci card because its impossible unless the card only has one port and even then it would be *under* the spec of sata2 by about 40mb/s)
which is the same as the 64bit card if the 64bit is being used at 33Mhz..
(which it probably isnt)
so this means that this 190mb/s mactron achieved is NOWHERE NEAR THE POTENTIAL OF THIS CARD
PCI 64-bit, 66 MHz: 533 MB/s
as
top speed for 64bit card at 66mhz would be: 533 MB/s
