Thanks Mark.
I think those 64MB drivers are sweet also, the only downside is the come at a hefty price premium. I can buy a 32MB 2TB WD drive for about 100 euro here. The 64MB version costs 180 euro. I'm not sure those extra 32MB's and half a new generation software update are worth it.

Also, what is your stance on Samsung HD's? They are usually a bit cheaper than WD, a bit faster and run cooler. (is there a catch?)
