It was also better since in the early days, our systemboards choked on DMA with faster CF cards. Nobody wants DOM! I did not rule out that Kingston's quality may have dropped significantly.

What ever killed the two Kingston Elite pro 4GB CFs within two weeks will also kill a DOM or industrial CF, maybe not in weeks or months, but probably within a year.
