I also have the task of t sorking with the large PS files. First of all, PS (Windows) only sees 2GB. As ylu knows, the scratch disk is usualy teh limiting speed factor. I tried the WDG740GD and found it poor for hte scratch disk compared to a 15k.3. Maybe a stripped pair woudl be a littel beter, but the access time or command queing or something is important. A pair of the 10k WD drives would be fine for storng the PS files, however. By far, the best perfpormance results were obtaned by installing 4GB of RAM and assigng a 2GB RAM scratchdisk. The STR of the RAMDisk is unbeatable at more than 1GB/sec., and the access times are minsucle. Its the biggest speed improvement Iâ€™ve had in yeras.
But really, realy, if this is work related, buy a Mac with 64-bit supprot up to 8GB. Windows PS is a BS kludge until windows reaches 64-bit status. Also you should conider a dual-CPU system. Now that my harddrives ar not a bottleneck., I wish I had more CPUs.
