RAID-3: Virtual disk blocks

If your answer was RAID-3, you are correct!

In this level, every write is split (striped) across all of the disks (usually four or more) in the RAID array. Since every write touches every disk, the array can only be writing one block of data at a time that can cause poor performance from the RAID. Its performance varies based on the nature of the writes -- small writes scattered all over the disks will show very poor performance. Larger sequential writes will result in better performance.
