If you're lucky. My generic media are better than.

I agree. For short term retention, data transfers between devices, files to have handy when away from your own computer, use SD or USB Thumb drives.

If you want real backups, setup actual backups using a server designed to store and use retention policies with an ongoing backup program (full, incremental changes, etc), a cloud service, archival grade CDR/DVDRs, tape media, etc. But don't use unreliable flash media designed to replace floppies and CDs.

Make sure you keep them away from magnets. Such as the Earth.

Make sure you don't bend them either, or look at them funny or they will lose your data.

I stick them in the microwave from time to time to keep them charged.

The only thing I can think is SD cards are slow and easy to lose

SD cards are fast enough.
Should one use them for backups?
In some cases, YES.

The biggest advantage is how they fit in everything.
Phones, tablets, ... can be very useful for fast crash-recovery ...

I'm not sure everyone understood that I had short-term emergencies in mind, such as when your normal backup device breaks. My backup USB stick gave evidence of failing yesterday, so I'll back up to my SD card until my new USB stick gets here. Especially since I have a disused card anyway. My last camera used an XD card, and I have had no use for it, because my new camera uses an SD card.

We ripped open a USB stick at work once. Guess what? MicroSD card coupled with whatever it needed to mate it with the USB-A interface.

Too funny. Initially we weren't sure if they saved money doing it that way or gallactically overspent. Not being a components guy, I never figured the answer.

yes, there is this build type, but it's rare. The majority of USB memory sticks have one, two or four big memory chips with dozens of pins soldered on a tiny PCB, plus a small chip that does the USB interfacing.
