How to read raw data off an SD card using a PC?

I have a custom embedded application where I’m saving large amounts of 16 bit data to an SD card in real time, simply using the card as an unformatted storage device. This works great - I can both save and retrieve fast and do it with a minimum of operating code - fat formatting would be a waste of time and program memory space.

However, of course I can’t access the data on my Windows10 PC as things stand.

I am looking for software that can read my stored raw data off the SD via my PC - suggestions would be much appreciated.
