FormData is way faster than the readAsBInaryString() especially when uploading large files.Actually no need to use the FileReader at all.
According to my test, uploading 6 files(each was about 4MB ) took me about almost 10s to convert the images to BInaryString ! And if use FormData the sending process is happend immediately.
So without using the FormData will cause a huge huge performance loss.Thus check if it is possible to use FormData,if possible should use the FormData preferentially.
