John, thanks for your answer and the link to the hard drive benchmark. I've already found a comparison between the WD1002FAEX and the F3 HD103SJ from Samsung. Performance is approx. the same, but the F3 is cheaper. Both drives are not recommended for a 24x7 use, but for my POC I think it's quite OK.
