Well I am in Canada... sometimes we don't get everything available in the US. When I was looking for 4tb drives the only one under 200 bux was a seagate. Apparently they have quality control issues.. lol. WD only makes faster ones like the black so they cost closer to 300.
I ended up buying a 4tb wd my essentials external hard drive which has an hitachi 4tb 5400rpm drive inside which was perfect for media player.
So yah I looked, the only low price one out there was the seagate. which I guess was the point of this article. My point was 3tb has been the sweet spot for a while and it feels like they've stalled out on making bigger drives.
