Reconfiguring Raid 5 array

Specs: Windows Vista
Hello all,

I just built a computer recently with a GIGABYTE GA-EP45-UD3R motherboard that offers raid 5 configuration. I initially set it up with 3 1TB 7200 drives. I did not create any partitions or anything for the OS, just installed away. Now, I want to add another 1TB drive to the array so I can have the extra space... so basically I can have over 2 TB of usable space.

In addition to this, I also got another 72GB 10000RPM drive that I plan to use as a scratch disk for Photoshop. How can I add this to the computer so it doesnt go into the array with the RAID 5 setup?

Basically, all in all, i want my 72 GB 10000RPM drive (to be used strictly as scratch disk) and then a separate raid 5 array with my 4 1TB 7200RPM drives for my OS and data.

Would I be best off to reinstall everything and maybe partition the OS away from the data? Is there any advantage to partitioning the OS in a raid 5 array? Can i install the 72GB 10000RPM drive separate from the raid 5 array without having to reconfigure? Also, can I install the additional 1TB drive to the existing raid 5 array?

I'm confused, but I know what I want for an end result. Thank you!

The 4th drive would not be part of the array as you state it. Just install it.

I use all my drives for scratch disks.

Any disk added would be outside of the array unless you use the raid management to add it.

I can tell you a single raid 5 array is partitioned as much as you would need it to be.

Partitions don't matter as much any more. It might if you have (I think the number is) 65,000 files in a directory or that many directory folders.

"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10
