We currently have 4 - 160's striped and have great success.
Look on M/S for information. Make yourself aware of the downside with striped drives. All procedures have +/- .
In that set up would l be able to have my O/S and video files on those same 2 drives? Or would it create a bottleneck as the VideoGuys website suggests and that I would also need a dedicated video drive?
I apologise if these seem obvious questions but I would like as a reliable and fast machine as I possibly can.
This biggest potential issue with Raid 0 is that if you lose one disk in the set, you've lost everything.
I don't think you can put the OS on a Raid 0 set - I wouldn't suggest doing it even if you could; get a 3rd drive just for the OS and leave your video on the Raid 0 set.
scottW is correct. We have our OS isolated on a separate drive. Its documented here that Vegas operates better on a separate drive, not a partition of the OS drive, but a physical HD. If we need to reinstall the OS, we just format the drive and install. Down time is minimal. Striping drives is definitely for video not OS.
