TMA said:I thought latency/seek times can be slightly higher on bigger drives but the difference wouldn't be noticeable. Correct me if I'm wrong.
It would be logical, but if you think about it, the disk is physically the same size, 3.5". So the drive head can move in the same amount of time. Sometimes latency might even be slightly less because all the data is closer together on the platter, so the chances of the head not having to move so far are greater.
reality
edit: and personally, I would go with the 250GB
