Well my Seagate 3TB(ST3000DM001) spilled the beans after 4 years(3 of semi-continuous operation) so I might consider this.

I really have good experience with WD drivers. Having a 2x1TB WD Black drivers for a long time, not that i need a gold one.

I'm a big fan of the WD RE and WD SE HDDs, I have WD Re 8x 4TBs in my windows server and they have been running for the last 2 years none stop for hyper-V environment and data and media server purposes without single issue. Good to see they now have an improved version with a combination of both the RE and SE versions(reliability and Performance), plus they now go up to 8TB, I would love few of those... I have had few WD Red's go wrong on me over the years in my NAS, random bad sectors and "re-identify disk" spamming the logs, but no data lose (thanks to raid 10). But WD have been pretty good on the support and replaced them quickly and efficiently, so I cant complain.
