DELL 7040N/A memory card reader module OptiPlex 7040 5040 3040 94D86

Dell OptiPlex card reader module

This genuine Dell flash memory card reader module fits OptiPlex 7040, 5040 and 3040 small-form-factor desktops. It installs internally to provide front-panel access for common flash storage cards. The green circuit board matches the original equipment design. Builders upgrading or repairing those specific chassis will find it a direct replacement.

Sustained transfer behaviour

The reader handles sequential card reads and writes at the speed supported by the inserted media and the host USB controller. No onboard cache or controller throttling is documented, so performance scales with the card class and system load. Extended batch imports from high-capacity cards proceed without thermal slowdown on the module itself.

Thermals noise and power

Passive operation means the module adds no fan noise and draws minimal power from the motherboard header. Heat generated during typical photo or video offloads remains low enough that no active cooling is required inside the chassis. The small-form-factor layout keeps cable routing clear of airflow paths.
