Problems with an SD card is that it will wear out even faster than an eMMC due to lack of FTL, and also friction fit instead of soldered connections means the part is susceptible to wiggling out of the socket and also corrosion between the contactors.
Not sure of the benefits of an SSD over an eMMC. Guessing the former will have a more sophisticated FTL and other things.
- JaimeThompson 7y agoMultiple companies make high endurance SD cards for things like dash cams and automobiles. Take, for example, WD https://www.westerndigital.com/products/embedded-removable-flash/automotive-sd-cards https://www.westerndigital.com/products/embedded-removable-f...
- castratikron 7y agoDidn't know that, thanks. But there's still the problem of a friction fit connection in an environment with a lot of vibration and contaminants. Seems like these would be good for use cases where the part needs to be removable and also have high write cycles, like a dash cam or data logger that has no other interface to a PC. Also the eMMC interface exposes quite a bit of the underlying hardware (see mmc-utils on Linux). With SD cards I think you're generally stuck with some kind of SMART interface.
