Quote:Over the past year or two external I/O connections have increased greatly in speed and have become easier then ever to use. This revolution originally began with the introduction of the USB port, which allowed users great speed and true plug and play support. It was very simple for the end user to use, just plug in your device any time and it’ll pop right up with the correct driver (in most cases). This was great for things like mice and printers, but external backup a greater speed was needed. So the obvious upgrade was USB 2.0, which was a faster version of the standard USB port. USB 2.0 is equipped with a max speed of 480Mb/sec compared to the 12Mb/sec of the first USB port. Also, another popular high speed external connection available is the IEEE1394 Firewire port, which operates at 400 Mb/sec. With the popularity of these connections growing larger and more computers having them as standard equipment the hard drive community saw a perfect opportunity to start pushing high speed external hard drives. Even though these connections are very fast, they still are no where near the speed of an internal hard drive. So if things weren’t already complicated enough in steps SerialATA with a 1.5 Gb/sec connection. The main purpose of SerialATA is to eventually replace IDE with a faster more practical method of internal conductivity. So you might be wondering why it’s a threat to the external drive market, well its also available in an external connection (e.SATA). It would seem that this would be the best method of hooking up an external hard drive because its main purpose is for connecting hard drives.
