David, I forgot a datapoint for one of your original questions.

I admin around 50 Seagate Barracuda IVs of the 40GB variety, around 15 of those are running 24/7, the rest are just desktops. I have never had one die on me, nor did I ever receive a DOA specimen, something that I cannot say about IBM DeathStars. 😟

Do note however that I have heard that Barracuda IVs loose around 75% of their speed if connected to a hardware RAID controller. Don't know wether this is true.

Something else: unless you really, really need the 120GB, then by all means use the smallest size disk you can get away with. The larger the disk capacity, the higher the power consumption. Heat ~ temperature ~ 1/reliability. This is especially true if you do not actively cool your disks with dedicated fans, can space them adequately etc. For the Barracuda IVs there is a definite step in power consumption in going from 40 to 60 GB, as the latter is a two platter design requiring a stronger motor.
