Hi,

What is best practice when configuring a RAID for a server.
More specifically, would you install a Operating System on a RAID 1 or RAID 0?

Then create a Virtual Disk for data

Thanks

raid 0 offers no redundancy and (in my opinion) an oxymoron
only use raid 0 for testing and if you don't care about the data

i have used raid 1 on my servers for the operating system and another raid level for data
either raid 5 or 6 if it's just a file server or raid 10 if it will have databases (exchange, sql, mysql, etc.)

You NEVER install an important OS (or store important data) on a RAID 0.  NEVER.  ABSOLUTELY NEVER.

RAID 10, fine, but NOT RAID 0.
