I've been using one 750GB hard drive to stream all my sample libraries, but I'm about to add additional hard drives to share the streaming duties (not RAID configuration). For example, I'll probably divide up an orchestral library onto different drives so each section is stored on a different hard drive.
So my question is, how many simultaneous streaming hard drives before the benefit stops, and the CPU/RAM limitations kick in?
I currently run a quadcore 2.4Ghz, WinXP 32-bit with 4GB RAM (3GB switch activated) on one DAW, and my other DAW (laptop) is running Core2 Duo 2.4Ghz, Vista 64-bit with also 4GB of RAM. I could upgrade the WinXP 32-bit to a 64-bit OS and add more RAM if needed, and if I choose to do that, what is the RAM to multiple hard drive streaming ratio? For example, is it something like 2 GB RAM = one streaming hard drive (so that if you add one more hard drive, it won't help any as the RAM will become the bottle neck. You'd have to then add more RAM to benefit from adding additional hard drives)?
