Nicolas, If you are reffering to hdb you are wrong because there is no device there.
So, If I sum up your answers then my HD is capable of 30MB/s. The UDMA(100) is a sales persons trick. My bus is 33Mhz and it is not holding back my HD. So, If I like to buy a new motherboard and a new HD, what should I buy? Assume that I would like to get the best a person might expect from a home computer.
