The life span of a flash disk is determined by the total amount of data that is
updated, erased, and rewritten each day. To calculate the life span, use the
following formula:
Life span (in days)
The Matrox Iris E-Series flash disk supports 100,000 erase cycles. The total data
update rate is calculated as the total amount of data written to the flash disk
multiplied by the number of times the update occurs daily. The result of this
calculation is the number of days in the life span of the flash disk.
For example, a 128-Mbyte flash disk, having a capacity for 100,000 erase cycles,
written at a rate of 10 Mbytes, 24 times in a day, would result in a life span of
146 years.
