Query: Ordered DV-516E, got DV-516D

I ordered the "TEAC DV-516E 16x Internal IDE Black DVD-ROM Drive" and got a box labeled "DV516E/KIT/B" but inside was a drive labeled "DV-516D". The DV-516D has a 256KB data buffer, not the 512KB data buffer that I expected when I ordered the DV-516E. The DV-516D worked well enough, but I decided to return it because of the deceptive packaging.
