Are SSD and Flash drives the same thing?

With the advent of cheap flash drives I was wondering what the real difference is? I saw a 256GB flash drive for $89 why cant (or can it) be used as a OS drive? Does it read/write differently? Im assuming because a SSD is on a SATA lane its faster than even say USB 3?
 
A flash drive uses one or two flash chips over very few lanes in parallell. In an SSD, more, smaller capacity flash chips are utilized in parallell, as many as 16 chips in a single drive. This parallellism contributes to vastly higher speeds and is also why the controller is so greatly emphasized due to the complexity of managing all those chips.

Thanks thats the info I was looking for.
 
sandisk has been know to use the same controller on their flash drives as in their budget SSDs, they usually trail a generation or so and as mentioned above fewer channels or a different nand configuration. Also the addition of a usb chip onboard

This is likely one reason why their flash drives usually perform so well:
