Default USB/IEEE external drives?

Ok, any of you have experience with external USB 2.0 or IEEE 1394 drives? Are they both comparable in speed/data trxfr rates? any particular brands to recommend? how is their speed compared to an IDE ATA/4 7200RPM disk?

thanks for the info.

IEEE 1394 is better without a doubt, and I like Western Digital for all my mass storage.

firewire is a faster throughput.

I've had excellent results w IBM, Seagate and WD drives.

Not so good luck w/Maxtor.

Firewire = serial, many packets at once

USB 2.0 = Parrallel, one backet after another

Firwire official spec is 400 Mbs
USB 2.0 is rated at 440 Mbs

But firewire rocks, there are many PCI cards out there now that have both though.

Funny thing is on paper I would tend to agree with you, but after losing both a seagate, and a IBM drive in the last 2 years while my old maxtors keep ticking away (no pun untended) I may have to reevaluate my position.

IBM was very good about getting me a new drive next day aired though.

Both firewire and USB are serial, plus you have your explainations of serial and parallel backwards. Serial is one bit after the other, parallel is many bits at once.

Err yeah I knew that, just flopped them, how it was explained to me anyways is that with USB it can only transfer a single packet at a time, and will wait till that packet it done before sending the next, to keep the packets in "order" where as firewire transfers as many packets as it can, then reorganizes them when the entire object has passed.

At least that's how it was explained to me.

USB 1.1 is rated at 12mbs. USB 2.0 tops out at 480mbs.

I've got a cheap AcomData USB 2.0 external unit based on a low-end 5400rpm Seagate drive, and it works great for general archiving purposes.
