RAID, or Redundantarrays of Lnexpensive Disks (RAID), is a fault-tolerant, inexpensive disk array.First, RAID-0Isometric mode-stripe for best performanceThis model is best if it is made up of two types of disks with the same capacity. This mode of RAID will cut the disk into equal chunks, and when a file is written to raid, the file will be cut according to the size of the block and then placed in each disk. Since each disk is interleaved with data, data is placed on each disk in equal amounts w
