Samsung makes pretty quality drives. I used to have one of their drives back in the Pentium days, no problems at all. However, their drives have a shortcoming - their firmware isn't optimized enough and it results in the slowest performance in the class. Samsung HDs are known as Intel IOmeter champions, it's a sign that they got good electronics, but firmware weaknesses result in 'low' regular Windows performance. Of course, they're not slow at all, but clearly slower than Maxtors and IBM ones, as far as I know.
