If a computer has two different physical internal hard-drives, whether a desktop, or a laptop that has a primary hard-disk and another internal drive connected say in place of the CDROM, would it be faster to read and then write from one drive to the other, or do read/writes to within the same drive achieve the same speed.
This question arises because I often need to re-rip (convert) a large multimedia file (>4GB) from one format to another, where the file is often demuxed into video and audio and then remux'ed into a single multimedia file. Preferences could be set such that the demuxed files reside on (and are read from) one drive and muxed (written) onto another drive.
What if I am using a second drive that is USB 3.0 and I have SATA 1.5? SATA 3.0?
