Hi Niraj,

QNX 4 does not support TRIM or similar technologies. And I didn't hear before about such technologies for Mag drives. If
 it possible customer should use software which work with disk more sparingly (decrease read and write operations, write
 is more significant here). Also customer may use industrial disks which provide more longer life cycle.

Respectfully,
Oleg
