Is Firewire that much faster than USB2?
Anyone know if 1 terabyte Firewire External Hard Drives are available at Yongsan? |

| ok, I just found out about Firewire 800 being the fastest of them all. |

One vote for firewire. USB is more universal, but when you transfer big files or large amount of data your PC comes unresponsive. Most of the times -at least with older computers- you have to wait until the transfer is finished until you can do other stuff. Firewire has its own memory controller and does not bog down your PC.
FW800 is available with only few Apple products. FW400 is fast enough, but eSATA would be better. Unfortunately eSATA is not that common yet. |

USB 2.0 is pretty fast and easy to find on any computer.
USB doesn't slow my system down at all, even transferring large files. |

if you will continually accessing your external HD, then i strongly suggest getting a Firewire interface. it's not as uncommon as you think (although FW800 is not that easy to find), most of the newer mobos have at least one or two FW ports. the overall performance of FW is significantly better than USB if you're going to be constantly accessing it.
if you're just using it to back up files, then USB will most likely be sufficient. |

| I believe firewire also gives better sustained data transfer rates for large files such as movies. |

I found this from Wikipedia:
| Quote: |
| FireWire 400 can transfer data between devices at 100, 200, or 400 Mbit/s data rates (the actual transfer rates are 98.304, 196.608, and 393.216 Mbit/s, i.e. 12.288, 24.576 and 49.152 MBytes per second respectively). These different transfer modes are commonly referred to as S100, S200, and S400. Although USB 2.0 can theoretically operate at 480 Mbit/s, tests indicate that this speed is rarely attained. This may be due to the peer-to-peer network architecture of FireWire (as opposed to the client-server architecture of USB), as well as its support for memory-mapped devices (which allows high-level protocols to run without loading the host CPU with interrupts and buffer-copy operations). |

Unless you can get Firewire 800, it seems like its better to go with USB 2.0.
Am I wrong? |

Much in the muchness.
There are a few nice drives with USB and Firewire.
I prefer to use firewire but that is my choice.
If you can get one with both you might as well. |
