My obsolete technology knowledge is rusty, but isn't he wrong here? You had two chains on ide, primary and secondary and within the chain you have master and slave, for a total of four possible drives
Primary master Primary slave Secondary master Secondary slave
If you wanted more drives, you'd have to go SCSI.
The jumpers didn't designate primary or secondary, the jumpers designated whether the drive was master or slave, if you selected the wrong designation, you'd have a conflict.
That's what made SATA so revolutionary, all the rules above were abolished and the possible number of drives was substantially increased.
I thought IDE just allowed two drives on a cable, where you had to designate one EVIL WHITE MASTER and the other NIGGER SLAVE or they'd conflict. But I didn't use PCs much then.
SATA is like the switch to having routers and a star network configuration, instead of a ring network. Each SATA port goes to one cable and one drive. Those big ribbon cables were a mess, and a source of failure due to all the connections they had to reliably make.
Yeah, you have it right, that's what I'm saying. Chain=cable.
You're both pretty much spot on. Generally there was two IDE controllers (which each provide one connector) per motherboard, and a master and slave drive for each controller.
SATA is definitely a step forward, but I've had more trouble with SATA cables and connectors than I ever had with IDE. Sure airflow is better, and cable management is so much nicer, but SATA cables have given me so much grief. With IDE you had two grades of cable: 40 pin and 80 pin, and you could tell the difference just based on the cable appearance. With SATA cables manufacturers cheaped out on early generation cables, so they ran poorly on newer drives. I've had SATA cables just stop working, the cable connector has just snapped, and I've even had the plastic tab from a SATA drive break off. Never had an IDE connector break to the point of unusability.
