SanDisk’s flash drives for iPhone and iPads

So as am writing this myself I didn’t know that SanDisk had iXpand Flash Drive for iPhones and iPads. This is partly due to the reason about how there is a lack of exposure for the same. People including myself have been wondering about the move Apple undertakes to sell devices with 16GB internal storage whereas this is totally avoided by other manufacturers who start their storage options from 32GB and even 64GB.
