I've found there's a certain amount of pot luck involved in HDD's.
I have still got an IBM Deskstar drive from the 'infamous' period that's running fine OTH I had a Seagate die after a year in a work machine. I got the Seagate as I'd been told by the supplier that my other choice (Western Digital) were suffering a high return rate.
What are the Samsung drives like, I've not seen much about them so does that mean they're reliable?
