IDE question

Lets say you have two ATA100 devices on ATA100 bus running on DMA100 mode. Can these drives share the bandwidth and be accessed simultaneously or could IDE access only one device at a time? SCSI can access multiple devices simultaneously and shares the available bandwidth of interface board.


I only got one answer in general hardware and I'd like more than one opinion/answers on this.
 
IDE uses a Master/Slave type policy, so only one device on a channel is accessed at a time.

Ding Ding! We have a winner! No wonder we have a FAQ man 🙂 I can't wait for Serial.
 
This is why it's generally recommended in an IDE format not to have both IDE HD's on the same IDE channel, but rather on separate IDE channels. If you want access to both, Raid the drives. If you want a decent access speed between both, Primary Master/Secondary Master.
