Great performance, very reliable. Noise is more an issue of how much background noise you have. In an open office you won't hear it. In home office or quiet office you will hear the whine.
The main issue is that they top out at 74 Gb. If you are into multimedia or video you may hit that quickly on a given project. I am assuming you are because 10k drives are great for two things; A/V or non-RAM resident databases.
