At the same time, Serial ATA is a drop-in solution that is compatible with existing ATA software drivers and runs on standard operating systems without modification. It provides for systems that are easier to design, with narrower cables that are simple to route and install, smaller cable connectors, improved silicon design, and lower voltages, which alleviate current design constraints in Parallel ATA. Configuration of Serial ATA storage devices is much simpler, with many of today's requirements for jumpers and settings no longer needed.
