BTW, my primary HD is the exact same SATA2 drive...
The object is to avoid the OS and Photoshop trying to access the same drive simultaneously.
Edit: cross-post, differing opinions.
The first partition is on the outer edge of the spindle and will be faster,
because the read/write head doesn't travel so far.
So when the OS and Photoshop's scratch start fighting each other, instead of writing to the closest available space, the heads will have to move from the outside to the inside, back and forth as the OS and Photoshop are writing to the drive. I'm pretty sure that using a partition for scratch offers no benefit and may even cause poorer performance. A scratch disk should always be a separate drive.
That's what I was saying. This is a separate drive we're talking about here. The OS is on the other drive.
Seems like I'm getting some conflicting info from people. Hope i didn't resurrect a sore subject!!!!

The files we work with are raw files from a D700 Nikon and can be anywhere in size from 12mb - 60mb depending on the number of layers, amount of detail etc...
some conflicting info from people
We're probably in area where opinion and taste matters more than fact :-)
As JJ pointed out, the really important thing is to have OS and scratch on different drives. How you configure the scratch drive is probably not all that critical.
I have, I guess mostly for aesthetic reasons B-) , a 100 GB scratch partition and the rest of that drive for image files before they go to external backup.
Also, does anyone recommend a particular company's partition utility? I think Vista Ultimate has one that comes with it....
Are your file sizes similar in size to mine?
we will have like 30 pics open at once in Photoshop
Yes, and bigger, but I don't have that many open. In any case, your scratch disk will be very busy, but around 100 GB should still be enough.
You can do the partitioning in Admin Tools > Computer Management > Disk Management.

My existing HD with the OS on it has a jumper limiting it to 1.5 Gbits per second. Any reason why I shouldn't take that off to get 3?
Also, I have 4 sata ports on my mobo (Asus P5kc) and one sata on the go port...which I really don't know what that is. all of my 4 "standard" sata ports are being used (two for dvd drives, one for HD and one for floppy drive)...where should I plug my new drive into???
Do I need to worry about the jumper thing? I'm so confused...please help!!!! I fear I am in over my head....
Meanwhile, I'm using a partitioning scheme across 4 internal hard drives that has my Windows operating systems and applications all on one Raptor 10,000 rpm SATA3 drive, the windows page file and temp files in the first 25GB of a second Raptor, and the PS scratch disk on the first 25GB of a 7200 SATA3 drive. The extra space on the latter 2 drives is largely used for archives, video captures and renders, extra image/video file storage, etc., while my 4th drive then serves largely as my workspace for whatever files I'm most actively working with. Optimum or not, I can't say, but it seems to work well for me.

I'd just rip it out, I never could see the point in that jumper.
Some older mobos only support the SataI standard, which is 150 mb/sec, but then you get that speed with or without the jumper.

Lose the floppy. In case you ever need it (not likely) you can borrow a slot from a DVD drive.
Daryl, your setup sounds great, but way to advanced for my noob self!
Thanks again to everyone for your help. As things progress, I may need more performance and may try and setup something like you have Daryl, but that won't be for awhile...baby steps for this guy!
Thanks again everyone, you guys are great.
