Two IDE Hard Drives plugged into a single IDE slot on the motherboard, do the two hard drives share the 130 MB/sec interface?

Hi, I have an IDE 160 gb hard drive I got for $12. There's a single IDE slot on my gigabyte motherboard.

I want to buy another and set up a software RAID 0, but I worry that the two drives will be sharing the 130 MB/sec and I won't get any performance increase.

I tested the first drive with crystal disk mark and got 70-80 MB/sec

Is the 130 Mb/sec for the whole shebang or per drive? Thanks!!!

For IDE interface, you cannot setup raid when it's connected to single slot/bus..
It is very important, that you only use one IDE disk per IDE bus.
Not only would two disks ruin the performance, but the failure of a disk often guarantees the failure of the bus, and therefore the failure of all disks on that bus.

Not even a software RAID in windows 7? So, to be clear, only one disk at a time can transfer date through the bus? If I abandon the RAID and just use one disk at a time, would that kill performance?

if you accessing both harddrive in the same time, then each your drive just can run at 66mb/s max..

kill performance..? not really..just slightly slower..
