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
