View Full Version : 8500 - Firewire or upgrade SCSI ?

05-16-2002, 12:12 PM
Having read the previous topics I am tending to lean in favour of SCSI. I currently run my 8500 with a NewerTech G4 450Mhz but am still using my old Ext Quantum Fireball 2Gig which had been rock solid for years.

Now that I have upgraded both the processor and the memory ( 448Mb) and the software, now Logic Audio 4.7 I would really like/need to upgrade my external storage.

I am not sure what my current Quantum is - SCSI 2 I guess ???

My friend has just bought a New G4 800 plus a Lacie Firewire and seems quite happy with it.

So I was thinking of buying a combo card ( Firewire / USB ) to allow me to go down that route plus take advantage of the newer USB devices also. I have heard conflicting comments about PCI speed ( 32bit) in the old 8500 that would restrict me to USB 1 ( as opposed to USB 2).

Now I am hearing that Firewire may not be the best option and that Ultra160 SCSI is.

My problem now is if I decide to go the route of Ultra160 SCSI will I need to buy a new SCSI adapater ( PCI card) and if so will I have the same issues with my PCI bus speed as I would if I go the FireWire/USB2 route.

Ideally I would like to have either Firewire or SCSI and the USB adapter but really only want to buy one PCI card, more for the slot space than cost as I will be taking up another 2 PCI slots with my video and Audio PCI cards.

Help !!!!!

This is one problem I've been procrastinating for quite sometime now.

While, I found a great bargain on a Adaptec 2930 (which is outdated 20MBps SCSI) and 1x Barracuda 7200 plus 1x Cheetah 10,000 (both 9GB 1/2 height, which I converted a ATX case to house them), I'm stuck with the "Hmm...USB and F/Wire devices, or stick with SCSI?" for future upgrades.

With our good old PCI PPC's humming along with XLR8 (or insert your CPU upgrade here:____________) upgrades, when will our Mac's cease to become useful to us? I mean literally, OS-X is gonna be what Apple is gonna stick with, and when all the developers of our favorite audio, graphix, publishing programs, etc.., finaly get sick of ensuring compatibility with pre-Yikes, Sawtooth's, etc....Macs, we eventually are going to have to bite the bullet and dump a few hundered-to- a couple of grand on purchasing a G4.

Granted, if you have the ATTO U320LVD card and all the drives necessary, then moving it over to a new G4 is gonna scream, but it's almost shooting yourself in the foot to invest in SCSI-2 thru Ultra2 SCSI periph's now that will eat up a valued PCI slot (which is why right now I'm sticking with my 9500).

Against my personal preference (though the pain that SCSI can be at times, I run ONLY SCSI devices and even though I don't have a full-blown MixPlus, my clients still come back), I would say go with a USB and Firewire combo card, just because you know that you can always move them over when the time comes that you'll be forced into a new G4.

just my $ .02

I have heard that combo cards do not work on older PCI busses

The problem is that one side or the other will work but not both

This I find quiet strange ???? Newer Macs come with USB and Firewire as standard - surely these types of card are designed for a market of older Power PCs ???

The only thing I have heard about combos is relating to the USB 2.O issue.

You have to weigh the fact that you can't boot from FW and it's nowhere near as fast against the expense and non-hot-swappable SCSI thing. Decisions, decisions! http://www.macgurus.com/ubb/eek.gif
