HD Spool Times

[Jeff Rothfus]

The original hard disk on my stock Duo 280c is finally driving me crazy.  

In an effort to improve battery life, I've told the hard disk to spool 
down frequently. But the time it takes to repeatedly spool back up for 
data access is becoming increasingly frustrating when compared to more 
modern machines.

I have a G4 tower at home, but the Duo is still in daily use for e-mail 
on the road. 

I'd be interested to hear suggestions from the group as to which upgrade 
would produce the biggest bang-for-the-buck improvement in hard disk 
spool-up times ...

[1] replace the stock SCSI 80 with a more modern SCSI 320?

[2] replace the mother board with a 2300, and convert to an ATA disk?

[3] boost the RAM to 32 Meg and run a RAM Disk?

TIA
