Anything earlier than v5 *may* be prone to difficulties reading discs later down the road. There are people out there who have launch units working perfectly fine, so I guess it depends how lucky you are. I don't remember the exact model numbers off the top of my head, but I think if you did a search on google it'd be fairly easy to find out. I'd say if you bought your PS2 isn't much more than a year old you probably have a v5+ unit, but I couldn't know for sure. :p
