Без разницы какой винт первый,

Вот, что написано по этому поводу в PC Hardware in a Nutshell:

Цитата:

Master
Connecting a jumper in the Master position enables the onboard controller. All ATA and ATAPI devices have this option. Select this jumper position if this is the only device connected to the interface, or if it is the first of two devices connected to the interface.

Slave
Connecting a jumper in the Slave position disables the onboard controller. (One of our technical reviewers notes that he has taken advantage of this to retrieve data from a hard drive whose controller had failed, a very useful thing to keep in mind.) All ATA and ATAPI devices can be set as Slave. Select this jumper position if this is the second device connected to an interface that already has a Master device connected.

Цитата:

Если винт сидит на одном канале с CD, то он работает на полной скорости, НО ровно до того момента,

Вы уверены? Спорить не буду, но вот, что я вычитал:

Цитата:

Try to avoid sharing one interface between a DMA-capable device and a PIO-only device. If both devices on an interface are DMA-capable, both use DMA. If only one device is DMA-capable, both devices are forced to use PIO, which reduces performance and increases CPU utilization dramatically. Similarly, if both devices are DMA-capable, but at different levels, the more capable device is forced to use the slower DMA mode.

Более того, что, возможно, интереснее:

Цитата:

ATA forbids simultaneous I/O on an interface, which means that only one device can be active at a time. If one device is reading or writing, the other device cannot read or write until the active device yields the channel. The implication of this is that if you have two devices that need to perform simultaneous I/O—e.g., a CD writer that you use to duplicate CDs from a CD-ROM drive—you should place those two devices on separate interfaces.
