OptiPlex Card Reader Module

This Dell flash storage card reader module carries part number 94D86 and fits OptiPlex 7040, 5040 and 3040 systems. It provides a front-access slot for removable media cards in compatible desktops. The green circuit board identifies the genuine Dell accessory. Buyers who need internal M.2 or PCIe storage expansion cannot use this module.

Passive Operation

The reader draws power directly from the motherboard header and has no fan or moving parts. It adds no audible noise to the chassis and its thermal contribution is negligible during normal file transfers. Office workloads see no measurable increase in system power draw. Builders who require active cooling for a storage device should look elsewhere.

Sustained Transfer Behaviour

Under continuous read or write cycles the module relies on the host system airflow for heat dissipation. Performance remains stable as long as the case maintains adequate internal circulation. Extended bulk transfers do not trigger throttling on the reader itself. Users who expect sustained speeds above the host bus limit will not gain additional throughput.
