I am talking about what is the optimal 2 hdd setup for both performance and some redundancy - special arrangement like this or some special RAID that gives both perf + redundancy on just 2 drives?
Haha you're fanny! Just add more memory and avoid page files altogether. There's a product like SuperCache that does Disk I/O level caching. All of course at the expense of reserving more memory for these operations. Personally I gave up page files after disk thrashing really put a burden on performance, especially when we're talking about compiling and linking 800MB worth of source codes every 15 minutes. The only reason you get "more" performance boost by putting the paging file on the second drive is that whenever you access your system the first disk is busy and the second drive is free to work. If you really think about this, to really get the benefits, at least for IDE "technology", you needed to put each device on its own separate channel. Basically one disk per ribbon. But then again, reality hits you again. We're talking about many orders of magnitudes of slowness because the disk is just so slow. You should look into borrowing memory from other systems over the network, if you're kinda cheap, since accessing them is still much faster than your local disks.
