So How Do We Make It Work?
The only way for this method to work is to put the first and second hard disks on separate IDE channels. That means the first hard disk gets hooked up to the primary IDE channel and second hard disk gets the secondary IDE channel. This allows both IDE channels can be active at the same time, delivering data from both hard disks concurrently.
In addition, the second hard disk needs to be at least half as fast as the primary hard disk. This allows the paging file on the second hard disk to be at least as fast as a paging file on the first hard disk. Otherwise, the performance advantage accessing the paging file concurrently on a second hard disk will be negated by the slower performance of the second hard disk.
Remember, if the first hard disk can serve data to and from both the application in use and the paging file faster than the second hard disk can access the paging file alone, then it is pointless to maintain a paging file on the second hard disk.
But if the second hard disk is more than half as fast as the first hard disk, then it would be advantageous to move the paging file there because the paging file can then be accessed concurrently with data on the first hard disk. In addition, the valuable outer tracks on the first hard disk will be freed up for use by the operating system.
Other Considerations
The trouble with such a setup is that most motherboards usually with only two IDE channels.
If you slave your DVD writer to the first hard disk (on the primary IDE channel), then you may have trouble writing data from the first hard disk to a DVD. This is because the IDE channel has to interleave its operations between the first hard disk and the DVD writer.
You won't have any trouble writing data from devices on the second IDE channel to the DVD writer though. This is because the DVD writer is on the first IDE channel and can thus be accessed concurrently with the devices on the second IDE channel.
However, if you slave your DVD writer to the second hard disk (on the secondary IDE channel), then you may have problems with games running off CDs or DVDs in that drive. Of course, this time you won't have any trouble writing data from devices on the first IDE channel to the DVD writer!
Either way, you will face performance compromises. It is a great idea but implementation is not quite as simple as you might think. The key to making this work is to be aware of such considerations and plan your setup accordingly.
But if your motherboard comes with enough IDE channels to give each device its own channel, then the way is clear - hook the second hard disk to a separate IDE channel and move the paging file there!
