Flash storage advantage
Flash Memory:
• solid state
• small size
• non volatile
• low power
• reliable
Flash Cards:
• mobile
• small form factor
• standardized
• interoperable
• shock & temperature endurance
• easy to use

Flash storage disadvantage
Flash Memory:
• price / MByte
• data retention
• data transfer rate
• limited erase cycles
• access restrictions
Flash Cards:
• „low“ capacity
• 7 different formats
