Flash Storage Drive Capacity Notice

 

Up to 7% of a Flash storage device’s listed capacity can be used for internal functions, and therefore is not user accessible. This is common in all Flash storage devices from all manufacturers. For example, a 32GB Flash storage device may only have 30-31GB actual writable data storage available to the consumer.

Flash storage devices are manufactured in this way to ensure the device operates dependably and in a timely reliable manner. Some of the data capacity is used for firmware, spare blocks and formatting, while other operations in the device may include:

  • Testing of storage capacity within the Flash storage device.
  • Identification of storage cells that have used up their lifecycle to ensure data is not stored to those locations on the device.
  • Additional special features such as security or copy protection.
