I would get a Western Digital. I have an old computer with a Western Digital from 1994, and it still runs fine 10 years later. I currently have an 800JB, and a 400BB, and both drives run very well.
I would get WD, however the store I'm getting it from doesn't offer a 80GB version. I've already spent a lot of money on other components so thats why I'm settling on either the Seagate or Maxtor-- So once again, Which of the two are better.
Western Digital hands down. 2 Maxtor drives have died on me, and the 3rd give me a "WARNING! IMMINENT HARD DRIVE FAILURE" message on boot up (not an important system mind you).
All of my WD drives are running quietly and quickly.
