Multiple concurrent disk transfers?

[Gouverneur]

I have a system with three physical hard disks.

I know that a mainframe can have 10 (perhaps more) I/O data transfers being done concurrently.

On a PC is it possible for two or more disk data transfers to be done concurrently?

Can a data transfer to printer memory take place at the same time that data is being transferred to/from a disk?

If not, is the problem the hardware or the OS?

You use a caching controller. Saves the data in memory until the buffer is full or time is available to make the transfer.
More of a hardware failing if everything goes in and out on 1 data bus. But there are some DMA transfers available, just not enough to make it really a multitasking system. At least not as much as the bif stuff. Ed Fair
