Q: I am setting up a RAID 0 array and a few other HDs that I will use. Since the raid increases acess time, it would be beneficial to have the OS on a non-RAID disk?

The reason why the OS loads slower on a Raid 0 is because the loading of an OS requires the reading of many small files. When you set up your striping, the smallest size that you select is bigger than most of the files that you will be loading, yet all of the data must pass through the Raid controller before it is read, which adds overhead. Additionally in some cases (in Raid 0) the drives cache is not as efficiently used as when it is a single drive. For OS and Apps putting each on their own single drive and independant channel will likely offer you the best performance. Raid 0 does do extremely well with very large files, such as digital images and video.
That's interesting !!! I was told that the OS on raid 0 was a better deal so I just learned something new thnx
Can I ask you if the same would be true for apps running on a raid set ??? I want to make sure I can run MAYA and get bes tposible response time cause it's a pretty intense app…

Re:No, from what I've heard for standard home computers, if you can set it up so you don't have your OS on the RAID partition you'll actually get better OS performance. I can't remember the reasons why but that's what I was told by a couple other people and it seemed to be true. I used to have my system running on 2x 30 gig hard drives in RAID-0, I swithched it b/c of my friends' suggestions and had my OS on a 20 gig drive and all my data going to the 2 30 gig RAID drives, and I did notice a increase in start up times and what not. However, that could've been due to the fact that I formated and did a fresh install when I witched everything around. All I know is I was told not to have my OS on my RAID partition. Hopefully someone with more facts/data/knowledge can come on here and give a better answer, but that's what I've been told
