Maxtor One Touch II - Firewire connection adequate for streaming MPEG?

I was hoping to add a 250Gb maxtor one touch ii with 16mb cache and 7200rpm to my winxp rig via firewire.  The plan was to use this drive to store videos archived from my dvr for streaming over cat5e to devices around the house.  

I am expecting that the only performance difference with this external drive versus a same spec internal drive would be the connection, firewire verus ?? (Internal).  Does anyone know if the firewire connection can handle streaming video throughput as adequately as a Ultra ATA/100 internal drive would?

thanks!

Check out this article from Adaptec (http://www.adaptec.com/worldwide/product/markeditorial.html?prodkey=io_comparison).  It explains the differences in the I/O technologies.  Firewire will work for your streaming media.  The speed is actually fast transfer than IDE.  Plus, Firewire supports isosynchronous data transfer.  The article explains this better.

If you don't already have the drive check this out http://www.bensbargains.net/#newsitem1112804289,26756,.  Follow the instructions get the drive for $120, that is the cheapest I've seen it.

As wordartist noted, firewire by default is faster than IDE.  You should be aware that there are no hard drives using native firewire interfaces, though - external hard drives that connect using firewire (or USB 2.0) have an IDE drive installed in the case, with firewire being the external connection between the drive and the PC.   As a result, the performance is close to that of an internal drive, and certainly adequate for streaming video at speeds close to internal drive speed, but there is some percentage of degradation due to the data being sent from IDE to Firewire to PC then to the network.  As long as the drive isn't handling requests for more than one video at a time, you should be fine;  if you want to be able to send multiple different video streams,  you'd want a higher performance solution, preferably SATA or SCSI based.

I'd recommend an external SATA configuration over Firewire - easy to adapt, very stable, and expandable in the future.  Firewire / USB problems have occurred in the past due to OS updates (remember XP SP2!).  SCSI is marginally better, but the price is still too steep for most private usage.  With the SATA, you will be running ATA-150 instead of the ATA-100 mentioned, and believe me, you WILL notice the difference.
