I also don't know what the new PCI Express 16 is, as opposed to AGP 8X. I had a computer business that closed 3 years ago, and now I am officially out of touch. I am about to upgrade the computer, and I am surprised to see boards with this "SATA" feature available.

Summary of changes:
1. AGP is now PCI express. Faster than AGP. PCI-e is not compatible to old PCI and AGP sockets.
2. IDE is now SATA. SATA (Serial ATA) is faster than IDE. Cable is not compatible with IDE (now called PATA-Parallel ATA). Power supply socket is also different. You will need a new power supply that has a SATA socket. Now it is SATA2, which is faster, but is still compatible with SATA. There's even a newer one which is called SATA300.
Check the motherboard you are buying. It should have SATA2 and PCI-e. You can still buy hard disks with IDE (PATA) or SATA2 interface. It will take some time before IDE becomes obsolete.

SATA is Serial ATA, and is not an extension of the IDE standard, rather, it is more closely related to SCSI. PCI Express is a new expansion slot technology, which allows extremely fast data transfer, although it's only being used for graphics cards currently, I imagine there will be other types of cards adopting the PCI express architecture

SATA is a new technology that is designed to transfer data in a serial fashion. IDE as you know transfers in a parallel fashion. A while back parallel replaced serial because it was much faster. The new SATA technology has designed a way to transfer data in a serial fashion that is much faster than parallel. The new SATA runs HDD's at 10,000 RPM's, compared to IDE's fastest of 7200 RPM's. So there is quite a difference in read and write times. Another great advantage of SATA technology is the very small diameter of the connecting data cable. This provides a great advantage when it comes to keeping good airflow and your system cool.

OK...IDE is a type of Bus...not the protocol like SATA is. I think what people are refering to is ATAPI (or ATA over Parellel Interface). SATA is just ATA over Serial Interface. So the speed of ATAPI discs has nothing to do with IDE since it's only an electrical connection.
Anyways, if you get a UltraDMA 6 ATAPI connection/disc you should be about par with the SATA connection as far as speed goes...the problem with SATA is that since it does not utilize a bus it can only attach one peripheral per node, unlike an IDE bus which can attach two...so you need twice as many ports. But the real-estate savings of the smaller cord is nice!

Serial ATA is a bit newer than the IDE stuff but both hard drives are still manufactured. A bit faster read time from the SATA and a lot of newer PCs stopped including the IDE connections.....go with the SATA if you can. :)

It is not IDE, it is meant to replace IDE. It is faster than standard ATA and eventually all computers will support it. PCI Express is the new graphics standard, meant to replace AGP. Again, speed is key - and it will eventually replace AGP in all computers.
