Will this work? SATA question

[SpongeBob]

Previously if I had a ATA/IDE drive with an OS on it I could simply unplug it and put it in another computer and bam! now I have access to it just like it was a backup drive where I could go through all the files on a partician or format C ect.

Will an SATA drive that has an OS be the same way? Just plug and play and it's now like an external disc I can sort through?

Thanks
