I understand the original post.
While the ops reasoning and possible lack of data to prove such a claim may not be to the level of some folks, I do understand the advice based on the ops experiance.
Case in point, My wires pc had WD drives, simply removing it from the pc was enough to crash it. No, if was a simple unplug and plugin after the fact.
At that point, my opinions of WD drives were formulated. My opinion based on a real life experiance. Since then I have never regretted moving to and staying with Seagate.

Subject: DO NOT BUY Western Digital "Green" Drives (also present in WD "Elements" external USB cases)
So, I can understand your frustration but, 4 discs out of how many thousands they make every day? That's not that conclusive. That said, iirc the reviews about a year ago did say that this was a very consumer drive. I don't remember hearing them break but...

BTW, Intel and AMD (and probably every other chip maker) does the same. Why not do it with discs.

I'm sure I can find someone saying the exact opposite about WD vs Hitachi if you look. It just depends on how many discs you run into.

If you had 10+ desktops with discs you kept needing to rma, I might see your point. But just 4 of the cheapest discs out there (unknown fs, no bench / profile data, kernel version, etc) and minimal troubleshooting data is very inconclusive to me.
So come again. Do not buy, why?
