..I have a striped raid0 array of 4 drives NTFS 512K clusters separate from the C: drive...fast like crazy (transfers 17 MB a second...sorry, showing off)...capture isn't a problem but when rendering, does Vegas 3 build the temp files on the same drive..? ...didn't want to set up 512 clusers on C: as well...it's 8K clusters now and I don't want to re-format...TIA...
