The distribution of RAM failure over time is different. Most failure of RAM
tend to be in the first few days or even hours. After that the rate drops
to a very low value for the next few years. In other words a long warranty
time won't cause alot of cost for the manufacturer nor benefit customers
much. But it looks good in advertisment ...
