A method and system of method and system of enhanced RAID level 3 is disclosed. In one embodiment, a method includes allocating three times a physical storage capacity of a data drive to a dedicated parity drive of a‘n’physical drives of a redundant array of independent disks, recovering n−1 physical drive failures of the‘n’physical drives through a parity-in-parity technique in which certain number of parities generated during an initial write of data may be physically stored and using an XOR function applied to the stored parities to recreate un-stored parities which enable recovery of the n−1 physical drive failures. The method may include creating a superior read/write access capability and/or a superior parity data redundancy through the mirroring. The method may also include recreating the un-stored parities after a time interval that may be specified by a user.
