I’m not sure which SD card was chosen in the past, but I do recommend upgrading to an industrial one (and not just high endurance), and they are typically purchased through electronics components retailers/suppliers.

One brand I use is ATP for my ruggedized systems[0]. Yes, they may be an order of magnitude more expensive than even a high endurance from SanDisk or Samsung, but I started using these in 2015 or 2016 and found they hold in harsh terrain, tolerate brown outs (these devices are solar powered and run off of super capacitors), and JustWorks(tm).
