Block Mode
Applications may access NVDIMM-Ns using standard ReadFile/WriteFile Block Interface APIs provided by the Windows SCM
Disk Driver. This allows existing applications to immediately take advantage of the NVDIMM-N’s high performance and low
latency without requiring any modifications. Please note that since the SCM Disk Driver uses Load/Store commands to directly
access DRAM on the NVDIMM-N, Disk Filter Drivers may not work. Please refer to the Microsoft video below for more
information.
