I think for the most part, people are saying the WD would be faster, thus agreeing with the benchmarks. However, I still contend that the user will not really notice that much difference in speed in real-world use. Maybe that's just me, because both my computers are fast enough to do what I need. One PC has Maxtor drives, the other WD, and I don't notice a difference. Of course, I also don't copy identical files on each machine and time them with a stop watch...
As for reliability you will hear of problems with any manufacturer. Personally, I have had both Maxtor and WD driver and have had no problems with either. In fact, I bought a Maxtor drive that was damaged from a guy who just got a new one, and Maxtor replaced it for me. I do tend to notice I hear my Maxtor more than the WD when I copy files from this PC to the server (Maxtor in the everyday use PC, WD in the server)
