I'm still probing
the limits of FireWire 800. For starters, the KIND
of drive used DOES make a difference. I've added
two additional drives to the SINGLE DRIVE TESTS to
illustrate this:
I found that when
it comes to SINGLE channel striped PAIRS (RAID 0),
running off a FireWire 800 PCI card does NOT put
you at a disadvantage to built-in FireWire 800.
That should be an encouragement to those of you
lacking built-in FireWire 800 on your Power
Mac.
But to squeeze
out the most speed, it's better to connect each
cable to the PCI card instead of daisy chaining
them, as you can see in this example using the
Maxtor DiamondMax Plus 9 in FireWire Depot case
kits and the OWC PCI card:
As I stated on
numerous occasions, to get the most out of FireWire
400 or 800 RAID, you should have a channel or
controller dedicated to each drive. The charts
below illustrate this. However, in the case of
FireWire 800, the single channel striped pairs
don't run that much slower than dual channel in
some tests (Photoshop). That's encouraging for
those of you without the luxury of multiple channel
setups.
