One other option is a SCSI controller card with a fast drive. I have
an ATTO card driving a 15,000 rpm SCSI hard drive with a 16 MB cache
on one of my Sawtooths. The largest drives like this are 146 GB (mine
is only 73 GB) so they don't give much more capacity than the ATA bus
but the performance is awesome and they are far less expensive than
Raptors.

I have a gigabyte ethernet model with a 250GB hard drive. I had to use the
Speed Tools ATA High-Cap Driver. Works great!

Native on the built-in ATA bus is 128 gb, but there is a high-capacity  
driver available that will get around this. If you stick in an ATA or  
SATA controller card there's no limit.

 Native on the built-in ATA bus is 128 gb, but there is a high-capacity
 driver available that will get around this. If you stick in an ATA or
 SATA controller card there's no limit.

Native up to and including QS 2001 is 131,072 MB.

Native for QS2002 and later is unlimited.

With the High-Cap kext, this can be extended to unlimited for most  
early G4 models and late G3 models (known not to work with 10.5.x).

With the LBA48 property work-around, this can be extended to  
unlimited for most early G4 models (works perfectly on my DA, and  
probably works perfectly on all AGP G4s).

Native for ATA to 100 is also 131,072, but there are no workarounds.

Native for all ATA/133 and the few ATA/100 cards for which there is a  
released update is unlimited.

Native for SATA is unlimited.

Native for early 1394 cases (with or without USB 2.0) is 131,072 MB.

Native for later 1394 cases (with or without USB 2.0) is unlimited.

It's not unlimited, it's 144 petabytes (144,000,000 Gb).  And before 
someone says it might as well be unlimited, that's almost certainly what 
  someone said about the 128 Gb limit... surprise, it's not.  True, it's 
unlikely to be an issue, by the time someone is building drives that big 
   most people won't know what PATA IDE is.

 
 With the High-Cap kext, this can be extended to unlimited for most  
 early G4 models and late G3 models (known not to work with 10.5.x).

I would say it's very large,  but it's definitely not UNLIMITED.



Just remember those other UNLIMITED values.
