RAID 0+1
Although the paging file will benefit from the increased read performance in a RAID 0+1 array, its write performance will be as severely degraded as it would be in a RAID 1 array. In addition, the paging file will not benefit from the additional data redundancy offered by RAID 0+1.
Therefore, it is recommended that you do not put your paging file in a RAID 0+1 array. You should place the paging file on a separate hard disk.
Moving The Paging File To A RAID Array
RAID 5
RAID 5's distributed parity requires a lot of calculations. Moving the paging file to a RAID 5 array will greatly increase the amount of calculations the RAID controller has to do. This greatly reduces its performance. Again, the paging file will not benefit from the additional data redundancy offered by RAID 5.
Therefore, it is recommended that you do not put your paging file in a RAID 5 array. You should place the paging file on a separate hard disk.
