A 1W LED is soldered to big heatsinking planes on the PCB it's mounted to, which is itself designed to sink heat away into the phone body. An SD card is wrapped in plastic, slides into a plastic slot, and touches the phone with only a few small pins.
Plus an LED behind a lens and cover on a phone or inside a flashlight is perfectly fine to run at 60C, but eject an SD card at 60C into your hand and you'll be throwing it across the room.

But I can say from experience that ejecting a 2.5" SATA drive with a metal case that's well over 60°C will cause you to drop it quickly. It's a good thing SSDs can handle falls without trouble.
