Compiler Error

1 - RAID exists in 7 standard levels, 0 through 6, all of which implement striping in various configurations, except for RAID 1 which implements a full mirror of the data set instead of using striping.
2 - Originally referred to as “Redundant Array of Inexpensive Disks”, RAID was renamed to “Redundant Array of Independent Disks” by industry manufacturers.
3 - Despite the existence of standardized RAID levels, implementations of those same RAID levels are completely proprietary, and no interoperability between major manufacturers currently exists.
4 - A cousin of RAID, MAID or Massive Array of Idle Drives, is an architecture that uses hundreds of drives, where latencies can be very high, but operational costs may be more manageable since not every drive needs to be online at any given time.
