The ones used for 4K recordings are not slow 100+MBps, I won’t say prone to failure as such, flash storage can only handle a finite number of writes but we can mitigate that by using wear leveling.
I wish SD Cards also had some specifications for random access speed.
I used to have a UHS-I SanDisk card which felt much faster than my current UHS-III Samsung card. It’s really evident when searching through the storage, waiting for photo thumbnails to cache, etc…
I am not sure whether to go for a UHS-I SanDisk or UHS-III Samsung next. That SanDisk might not handle higher bitrate 4K.
Aren’t SD cards slow and prone to failures?

That’s pretty slow for terabyte sized storage. And slow compared to the alternatives, too (600 MB/s or Gabs/s).
Spinning hard disks are faster than this, too. Have been for decade(s).

Hehe, I think I haven’t caught up with the improvements, flash with 1GB/s transfer speed is ludicrously fast!
All SSD and NVMe are also “just flash”, and reach 5GB/s and more, often limited by the available interface bandwidth until very recently.
Other formats can exceed that by caching & writing to multiple chips at once i guess.
