ADVANTAGES

HIGH CAPACITY: Holographic storage devices having 125GB capacity has already been realized. Eventually these devices could have storage capacities of 1TB or even 1PB.

HIGH TRANFER RATE: Early holographic data storage devices have transfer rates up to 40MB/sec .It is expected that it would have transfer rates up to 1GB/sec

PARALLEL SEARCHING: Holographic data storage enables rapid parallel searching as data is stored and retrieved in parallel. Hence searching is very fast.

REDUNDANCY: Because a single page of bits may be stored at one time, the information content of the page is intermingled. Thus any defect occurring in the recording medium would not destroy the data bits .Rather, only the signal to noise ratio is affected.

BANDWIDTH: Bandwidth is the amount of information that can be contained in Individual channels.
