6.8.5 Life of CompactFlash card

Life of CompactFlash card
(a) Calculation of life
The life of a CompactFlash card can be calculated as follows:
Life of CompactFlash card (years)
Total writable size (G bytes)/write size per year (byte/year)
(b) Total writable size
The total writable size of CompactFlash card is as follows:
Model
QD81MEM-512MBC
QD81MEM-1GBC
QD81MEM-2GBC
QD81MEM-4GBC
QD81MEM-8GBC
* 1 The total writable size means the total size that can be written until a CompactFlash card reaches
the end of life (the limitation of writing).
For the life of a CompactFlash card, refer to the following.
Model
GT05-MEM-128MC
GT05-MEM-256MC
Table 6.19 Total writable size

Total writable size

0.5G byte (512Mbytes) 100,000 = 50,000
1G byte 100,000 = 100,000
2G bytes 100,000 = 200,000
4G bytes 100,000 = 400,000
8G bytes 100,000 = 800,000
