I never have. In general though Seagate has the better reputation for quality, however Western Digital isn't bad either. I mean maybe its cause I don't play my PS3 much, but I don't get what the point of upgrading the hdd would be? I mean I only have the 80, but that seems to be pleanty. Granted I do use my 360 a lot and only have the 20 and its getting quite full, so who knows maybe as I use my PS3 more it will become more clear to me.
