Can I use SATA & PATA Simultaneously?

I got a new MB with PATA and SATA 150, can I use Both at the same time? Has anyone tried this? My MB manual doesn't have any info on this.

 

Yes.

I have done this.

 

I'm gonna stick my neck out and say YES by virtue of design criteria. "Simultaneously" may be a slight misnomer. The SATA is just another controller/drive/bus setup. Older mobos have twin IDE controllers (normally one for HDDs and one for optical drives) and a floppy drive controller. These drives coexisted to make a system functional.
It doesn't make sense to put both types of data transfer designs on a motherboard if they won't work together. The competition among mobo manufactures is too tight to throw extra hardware in just to give customers an "either/or" option.
Caveat: I could be all wrong. My opinion stated above is based on my understanding of economics and the marketplace - NOT computer science.

 

There is no problems with using both. It's done quite commonly. Just don't try to use RAID and join a PATA drive with a SATA drive. It can be done, but it's not a good idea. Using them both as separate HD's is kinda expected right now since we're slowly transitioning from PATA to SATA.

 

Yes.
