There is no "Flash drive" in the iPhone. It's a Flash memory chip that the OS accesses with its own Flash manager via a Flash memory controller.
The type of NAND Flash memory used in the iPhone could have anywhere from about 20 to 60 MB per second max read speed per die. No idea if they're interleaving access between die, which could double that or more in a larger GB device... but I think someone would've noticed that more memory = more speed in that case.
(The controller chip itself can supposedly go up to 666MB per second, if it's given individual die access to a 256GB array.)
I looked but can't seem to find any file access speed tests for iOS devices. Anyone know of some?
