CHAPTER 3: Setting Up and Getting Started RAID 5 stripes both data and parity information across multiple drives. Striping across drives improves overall performance, and the parity information provides data protection. Because of the error-correction capabilities, if a drive fails, the data can be quickly and automatically fixed. RAID 5 A1 A2 AP B1 BP B2 CP C1 C2 RAID 10 (also called RAID 1+0 or RAID 1&0) contains sets of RAID 1 mirrors acting as drives within a RAID 0 striping array. With this setup, the array could survive one drive failure in each mirror array. RAID 0 RAID 1 RAID 1 A A C C E E B B D D F F Drawback A RAID 5 array is treated as one drive with the capacity of all but one of the drives added together. RAID 10 treats the entire array as a single drive with the storage capacity of the smallest drive × 2. So if you have four drives (350 GB, 300 GB, 250 GB, and 200 GB) in a RAID 10 array, your computer recognizes a single drive with 400 GB total capacity. 32
