dc, do you have any data on how much difference a fast SCSI drive makes
in a MDD or similar G$ Mac? I just installed one and I have used Disk
Speed Bench X to test the transfer speed. I find 80MB/sec. My original
IDE Hitachi Deskstar on the ATA100 bus is only moving about 50MB/sec.
However, another WD drive on the same ATA 100 bus is also moving 80MB/sec.
I was hoping the 15K U320 SCSI drive would easily beat a good IDE drive,
but that does not appear to be the case. Is it maybe the kind of test
Disk Speed Bench X performs?
Another related point - AFAIK the fastest SCSI card made for a PCI slot
is U160. The U320 cards are all PCI-X or later. Those work in a PCI
slot, but only at 33MHz and 32 bits. The PCI SCSI cards, at least the
ones from ATTO Tech, actually use the 64 bit wide PCI bus in old Macs.
Maybe the only PCI cards made that do.

alright everyone i am using leopard 10.5.8 on a dp 1.25mhz mdd with 2
gigs of ram, any tweaks that you would suggest, any ways to go about
kernel hacking and trimming my system?
The easiest, cheapest and safest things to do with your MDD:
1. Download and run Monolingual. You can trim more than 2 GB of
unneccesary languages and architectures out your OS, it will run much
better. It's free.
2. SCSI PCI cards and SCSI hard drives are cheap now that most people
are using SATA or SSDs. A 15K SCSI drive with a 16 MB cache is an
awesome upgrade, around $50.00 for used 73 GB drives.
3. If you add another hard drive (of any kind) and use Carbon Copy
Cloner to clone your original drive it will defrag everything in the
process of cloning. Apple claims you don't need to defrag OS X but I
always felt mine ran better after using TechTool Pro to defrag files.
