Speed rating of a SD card


Is there a tool that would enable me to read the speed rating of a SD card?
Corollary question: is the speed rating written in the device descriptor of a SD card?
Thanks!

There are even some hard drive tests that might work.


I tend to just take a large file and see how long it takes to copy. That isn't really a true test since in actual use, many files are quite small and also involve write and read at the same time.

They are becoming a rather slow media. Not sure why but so much attention is being put on ssd's maybe. Many are still faster than a hard drive.
