What’s the difference between a Flash Drive and SD card?

Obviously the form factor is different, but I have a USB adaptor that I use with a 32GB SD card, so that both it and a 32GB Flash drive are not only comparable in amount of storage, they can both be plugged into a standard USB port. Is there any difference other than the shape and type of connector (which, as I noted, is negated by the USB adaptor)? Does one have an advantage in speed over the other?

I’ll add two more differences. 

 

One, it’s easier to carry around a flash drive, because that is typically what they are designed for. They can usually clip to a lanyard or keychain, which makes them much easier to keep track of than an SD card shoved in your pocket. Plus, if you were just to shove an SD card in your pocket without it being in a case, there is a chance you could damage the connectors. 

 

Two, flash drives work with some devices/OSes that an SD card will not. Pretty much everything will recognize a flash drive, even where they won’t recognize an SD card. One example of this is that I just replaced the HDD on a PS4, and to install the system software I had to use a flash drive; it would not recognize the update file when using an SD card with a USB reader. Related to this, you can usually boot a PC from a flash drive, but not an USB SD card reader.

Differences Between USB Flash Drive vs. SD Card

"The USB flash drive versus SD card: they’re both small, portable and used to transfer and store files. Their differences are noteworthy, but they are hardly rivals in the world of NAND flash storage. It is important however to distinguish what makes these memory formats unique so that you can use each of them to their fullest potential."

Flash Drives are removable storage devices equipped with flash memory capabilities and a USB connector. but SD Card SD card also uses non-volatile memory like flash drives.  SD cards are an integral part of many devices including digital cameras, phones, MP3 players and game consoles.  The average SD cards offer 1GB, 2GB, 4GB and 8GB etc.
