www.gateway.com Drawback RAID 1 treats the entire array as a single drive with the storage capacity of the smallest physical drive in the array. So if you have two drives (300 GB and 250 GB) in a RAID 1 array, your computer only recognizes a single drive with 250 GB total capacity. RAID for both: performance and security RAID 5 uses striping (at the block level) with on-the-fly error correction across all drives. Because of this error correction, small file read/write errors can be quickly and automatically fixed without a significant drop in system performance. RAID 5 offers good performance and data redundancy. This array preserves your files if a drive fails. 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 35
