Abstract
Methods and apparatus for accessing a redundant array of independent drives (RAID) storage device are disclosed. In some embodiments file data is broken into multiple segments. A cryptographic operation is performed on one or more segments to generate encrypted segment(s). One or more parity syndrome is computed from the encrypted segment(s) and the unencrypted segment(s). The encrypted segment(s), the unencrypted segment(s) and the parity syndrome(s) are striped onto different individual drives. Since the cryptographic operation is not performed on all the segments, it may also be performed concurrently with computing of parity syndrome(s) from other unencrypted segments.
