Author: Chris Rogers Date: 1999-01-08 19:35:00As a rule you should get better performance if your programs and data are stored on different physical devices, but the disc controller and size of I/O buffers will have some influence. If both discs are logical partitions of the same physical device, you are not so likely to see much difference, except that the OS will probably use different buffers. However, if you are running a system with intelligent disc controllers, particularly with UNIX, you may not see any difference at all. The reason for improved performance spreading over different discs is that the read/write heads have to move for each access, so splitting reduces contention. Tricks like disc striping also increase speed. In the end, it is all a matter of experimenting until you get what you want, though unless your jobs run for hours and are I/O intensive, you may not see the difference.
