    RAID: Redundant Array of Independent (or Inexpensive) Disks. Type of disk, often used on servers, where several physical disks are combined into an array for better speed and fault tolerance.
    Level 0 implements data striping where file blocks are written to separate drives. Does not provide fault tolerance, because failure of one drive will result in data loss.
    Level 1 implements data mirroring. Data is duplicated on two drives either through software or hardware. Provides faster read performance than a single drive.
    Level 2 - not used in practice. Data is split at bit level at written to multiple drives.
    Level 3 - requires at least 3 drives. Data block is striped at byte level across drives and error correction codes (parity info) is recorder on another drive. Provides fault tolerance but slower writing performance.
    Level 4 - Similar to Level 3 but provides faster performance because it uses blocks for striping.
    Level 5 - Similar to Level 4 but improves performance but also striping parity info across multiple drives.
    Level 6 - Similar to Level 5 but also uses second parity scheme for better fault tolerance.
    Level 7 - Proprietary RAID design by Storage Computer Corporation. Faster than other levels because it uses multiple levels of cache and asynchronous I/O transfers.
    In addition multiple RAID levels can be combined to improve performance or reliability.

    but now a days after arrival of new SATA drives makes this technique more reliable and worth able.
    this makes the new generation computer in the market

    Raid is Short for Redundant Array of Independent Disks, a class of dicks drives that apply two or added drives in aggregate for accountability altruism and performance. RAID disc drives are acclimated frequently on servers but aren't about all-important for claimed computers. RAID allows you to store the same data redundantly in a balanced ay to improve overall performance.

    To know more about RAID Drives; just follow the below URL of wikipedia. I am sure you will get the answer rest of your all questions related to RAID.

    I searched in google and then found out that only there are 6 raid levels and we have 01,10 raids.
    So, from does level from ? Is it 10 or 01 or something else ?

    RAID (redundant array of independent disks) is a way of storing the same data in different places on multiple hard disks.

    RAID is now used as an umbrella term for Computer data storage schemes that can divide and replicate data among multiple physical drives.

    RAID (redundant array of independent disks; originally redundant array of inexpensive disks) is a way of storing the same data in different places (thus, redundantly) on multiple hard disk.
