thanks for the replies. Sounds like there’s definitely a speed advantage to separating read and write operations physically through drives.
@Dave:
How much faster would set up #3 be than set up #1 if I separated read and writes? Â Also what happens behind the scenes with reading and writing when I’m editing but not rendering or exporting? I’m assuming minimal writing and mostly reading.Â
Re: SSD drives, glad to hear they have 5 year life. Warning – long question. If I was constantly copying source files on the drive and deleting then once I’m done with a project, even if the source files were relatively much smaller than the drive and I always had a bunch of free space on the drive, the way SSS writes writes data, would  I still quickly fill up the free blocks on the drive and cause it then to slow down in performance?
@Nigel:
Thanks for the tip. Since I would have my source media on the read drive and would already have a backup for that. I’ll skip raid 1 and would either do Raid 0 or just a single HD (or even an SSD).
I’m curious about your system b/c I was considering a i7-970. I was told that w 12GB RAM (which was max on that system i could get) it would be slower than i7-2720QM with 16GB RAM for video editing all other things being equal. Any thoughts?
Here are the only benchmarks I could find.Â
