For very small copies, this may be faster since it doesn't bother looking at alignment. However, if intrinsics are enabled, many compilers will identify the code as a copy and use an intrinsic instead (an inline memcpy.)

(See previous comment. Also note that years ago, especially for very small memory usage, many embedded developers wouldn't use the CRT; they wouldn't use libraries of any kind. This wasn't arrogance, but that they had to control every aspect of the code. Even today, I deal with many serious problems where third party libraries are used, including STL and Boost.)
