One last question on this...
I my current setup I'm down to a choice to make for my Softsynth Library files. Which would be the better option?.
1: Put them on a dedicated, non-partitioned 80GB HDD at 5200rpm
2: Put it on the 2nd Partition of a 1TB 7200rpm drive (1st partition reserved for Sonar Audio)
and would the difference be significant?
Several folks have posted what I am about to say - there is no realistic performance point whatsoever in creating logical partitions.
All of the SATA 3 drives are plenty fast - 7,200 rpm is a better spin rate and more desirable than 5,200.
An SSD is much faster than a non-SSD SATA 3, but either has plenty of horsepower to avoid bottlenecks in Sonar.
If I ever see a need for it, I will add a third internal drive. Right now, I use 2 - both are internal SATA 3 3.5" non-ssd drives. I split them by OS and programs on the primary drive, and samples and projects on the 2nd drive.
That works great - I never have any data issues or performance issues, and with the money I saved on returning a 512 GB SSD drive that crapped out in the first 3 months I owned it, I was able to buy another 16 GB of memory, a 46" HDTV, and 3 new pairs of Nike basketball shoes from the outlet store.
But back to my original point - you are better off buying a bigger case if you need it, and adding one or 2 additional SATA 3 drives - SSD or not, than you are by partitioning yourself silly.
