Nec nd 3520 + 3520a dvd writer

Hi people,

just a quick question, whats the difference between the Nec ND 3520 and same model but with letter A on the end. Ive seen there are 2 models on the market 1 3520 and 1 3520A?

Please can anyone tell me the difference.


If there is a difference, it ain’t much.

For the 3540 you just ignore the letters, think it’s the same for the 3520.
