crack open a LaCie and inside you will find a crappy 3rd rate hard drive that they didn't make. I know this from experience.
They are over priced. All you have to do is grab yourself a western digital or even better a seagate and a good case. External drives are simple to put together and you'll have the top of the line hard drive for about 65% the price of a crap box LaCie.
LaCie is cheaper than G-Tech, whose the defacto video professional's standard. Many have cracked open their LaCie drives and have found Seagate Barracudas, Western Digital Caviars, and (back in the day) Maxtor's (who I do think is crappy)
Out of the four LaCie drives i have, two of them have Western Digital HDDs the 2Big has Seagates, and the old d2 has Maxtor.
All of my G-Techs have Hitachi's.... because that's all they use.
