I think since both methods of either buffering in memory and then writing all bytes at once OR writing a byte at a time are both slow it makes me believe is the hardware. I tried the tests that you guys suggested and the pushing files to it is slow as hell. I am assuming that means the good ol' card is dying - I will replace and verify but most likely that should be it.
