Digital Files vs. Wedding Album / Prints

Ever wondered how long a digital storage device will last vs prints? Here are some interesting findings:

CDs and DVDs: 5-10 years unrecorded, 2-5 years recorded
Blu-Ray: Not certain, probably over 2-5 years recorded
Hard Disk: 3-5 years
Flash Storage / USB: Depends on write cycles, 5-10 years or more

PRINTS and albums: 100-300 years. Which makes prints and albums the best and perfect option for family heirlooms.
