Please log in for more thread options There is no regular ATA vs Ultra ATA, they merely worded it differently and both support UDMA, ATA33/66/100. IDE1 and 2 also support PIO mode and ATAPI, so an optical drive for example would need be on 1 or 2. The difference appears to be that the 3rd & 4th are provided by a discrete controller sitting on the PCI bus. That makes any devices connected to these 3rd or 4th, slower. Leave the drive connected to 1 or 2 if the performance matters. It may easily not matter if only store, rather than work with common files such as video or music playback which have playback requirements of a data rate still lower than the performance would be. | |||||||||||||
