The read speed is slow enough that it causes my car's infotainment system (2019 model year) to sometimes hang up

Extremely slow download speeds.

When writing music onto it from my Windows computer, the write speed was slow enough to repeatedly drop the data transfer rate all the way to zero

terrible backup speed

Very slow speed.
