It is not difficult to support fault-correcting redundant storage 
using already available free mechanisms.  It is unlikely that these 
existing mechanisms will still be in style in 50 years.  When talking 
to the Holographic Drive vendors, it is best to ask them the tough 
questions about media errors, redundancy, and long term support. 
Without these, long-term holographic storage will be just another 
mirage.
