Had issues with a few WD Green's, so I would avoid those at all costs.
I have had a pair of greens running raid 1 flawlessly for roughly 2 years.
I now run 2x3tb WD Reds which are shaping up to be fantastic drives.
WD have a really good rma system if there is a problem but in the many years I've been running WD drives I have never had to use it.
All HD's can suffer a failiure and I don't think one brand is more failiure prone than another. So I certainly wouldn't 'avoid at all costs' based on one user's experience.
USe the links Kia posted just to check the hard drive you selected is on their compatable list.
