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!
