Calling all Video Editors and Photoshop Pros

On which drive do I place my scratch disk?

I've got a 90GB SSD and a 1TB Samsung Spinpoint F3R HDD.

The plan is to place the OS and Apps on the SSD and data on the HDD

I have 16GB RAM and could create 12GB Ramdisk for scratch if that would help

The CAD, Sketchup, Photoshop and Illustrator files are not that big...mostly under 100MB. I've captured raw MPEG4 AVC/H.264 footage but have yet to do any editing...but just family stuff which I'm looking forward to.

Should I leave the SSD for just OS/Apps and partition 200GB on the outer edge of the 1TB HDD for scratch and the rest for data?

What is your recommendation? Thanks!

I think a RAM disk would be a good solution for scratch, given that you clearly have enough RAM. I would not make it as big as 12 GB, but maybe 8 GB, which would still suffice given the size of your files. I think this would really be faster than any scratch on the regular HDD.

As for the SSD, their life-span is limited by the number of read-write operations, so not only I would not place the scratch there, I would also move the Windows temporary files and possibly "C:\Users" folder away from it to the HDD. Some people also move the pagefile either to a RAMdisk or to the HDD, there is a tutorial about it here on the forums.
