JBOD
When the hard disks in a JBOD array, they act exactly like a single logical drive. Therefore, placing the paging file here will not incur any benefits at all. It will just be like putting it on the first hard disk.
Conclusion
Generally, placing the paging file in a RAID array is not recommended at all. The only situation where a RAID array can actually improve the paging file's performance is if the RAID array was created using RAID 0. Otherwise, avoid placing the paging file in a RAID array.
How To Place The Paging File In The RAID Array
To the operating system, the RAID array appears as an ordinary logical drive. Therefore, moving the paging file to the RAID array is as simple as moving it to another logical drive. Just follow the instructions for moving the paging file to a different logical drive.
Moving The Paging File To A RAM Drive
A RAM drive is nothing more than a logical drive created out of system memory.
To the operating system, a RAM appears as a normal logical drive, albeit a very fast one! Because it is created using system memory, a RAM drive is fast. VERY fast, in fact. As I mentioned earlier, even dual-channel PC2700 DDR memory is over 70X faster than the fastest hard disk.
That's why many people actually advocate moving the paging file to a RAM drive. Their reason is simple. Because a RAM drive is so fast, moving the paging file there will greatly improve its performance.
They are most certainly correct. Moving the paging file into a RAM drive will definitely give it an enormous boost in performance. However, that is really counter-productive. Let's see why.
