So we know that a hard drive gets slower as more data is put on it. So at what point does it slow down? Lets say you have a hard drive with 4 platters. When you add data, is the data broken down divided amongst the 4 platters or does it get put on the first platter and when it fills up then data goes on the second platter and so forth? This is an interesting question that nobody has addressed. Hard drives of the same size can have different sized platters and therefore have more space on a single platter or less. For example, the new breed of 1tb drives all have different platter sizes. The samsung 1tb will have 3 platters at 334gb per platter but the hitachi has 5 platters with 200gb per platter. So which will be faster? Depends on how data is applied to the platters right? So does anybody know the answer to this?
