| Issue |
Most of the Flash memory devices have a limitation on the number of write accesses (for example, 100 000 times). Is the QNX flash driver designed to over come this limitation?
Is there any optimization that has been done to prolong the device life time? What will happen if we reach to this limitation?
|
| Solution |
The newer flash devices don't really bother with this. The number of writes to a flash device is extremely high. That said, you might still hit the limit if you have to write a lot of files.
To prolong the life of the device, the driver does have optimization code.
If you reach the limitation, the device becomes read only. |
