External drive is a good suggestion, but I am going to consider internal drive first because it is easier to carry around with me.
The fitability (is that even a word) is the problem. I am sure it is a 12.5mm drive, but I am not sure what the SZ is using. Any idea where I can find the info? Sony website does not help at all. I am thinking maybe the other owner of the same notebook will be able to help.
Also, there is another concern. The problem with the SZ series is that the faceplate on the drive is different from regular optical drive. It has a curvature of some sort. I know regular drive is all rectangular. That is why I am trying to ask around, if somebody has actually done this and if there oem drive would fit at all. I wouldn't mind if the look would be weird a bit, but more concern towards how it would fit in the slot.
