We also have a considerable number of 'small' (100-500 MB range) drives that have been displaced by upgrades to GB sized drives. Bothering to install a bunch of them in a machine to get what is considered a reasonable amount of memory now-a-days does not seem worthwhile when you look at how much a new 3, 8, and up GB drive costs. They are not even big enough to write a ISO9660 image on to be used as a temporary storage for machines with CD writers. However, they are just about the right size to be used as a swap device. Unfortunately, I am not enough of a hardware guy to know what kind of performance increases we may or may not get from using old IDE drives in such a role. So my question is, on an all IDE system, how much of a performance increase does one get by moving the swap from a partition on the same drive that contains the OS and user data to a separate, dedicated swap drive? Does the performance depend (significantly) on the way the IDE devices are configured (what is primary/secondary or master/slave)? Thanks for any educated responses or pointers to good info sources on the topic. -- Crist J.
