This module contains the Internal Dual SD Module (IDSDM) and vflash card that are combined into a single card module. There are two
SKUs available:

• vflash + IDSDM
The IDSDM with vflash module has a dedicated slot at the back of the system chassis. This is a Dell-proprietary PCIe x1 slot that uses a
USB 3.0 interface to host. In the system, the IDSDM and vflash card size changes from SD to microSD and the supported capacity for
IDSDM microSD cards are 16 GB, 32 GB, or 64 GB, while for vflash the capacity is 16 GB only. The write-protect switch is built onboard the
IDSDM/vflash module.
