Which function is best for gaming?
and is it noticeable ?
Level 1 -- Mirroring and Duplexing: Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.
NO there is no increase in speed for raid 1. You are thinking of a raid 1+0, or raid 5. That is where you have a raid 1 mirrored for data protection, but you need 5 drives..
well raid 1 isnt the fast option either, which was sorta my point.
There is no speed increase on RAID 1 during write operations because the write is being done to both drives, but for read operations it can do the same concept as RAID 0, because it is the same data. Each hard drive reads a chunk and the controller puts it together in the right sequence. There is only a speed increase on read operations so loading times would be better.

get RAID 0+1 uses 4 HDD but provides the best of both worlds
Get a good raid controller (or check if your onboard one for raid 0 does stripe + duplex) and two drives and do raid 0. That's the cheapest and easiest way to get redundancy and performance.
