It's as if billions of kilobytes cried out at once, and then were silenced.

Hitachi just announced a One Terabyte 3.5" hard disk, which sounded great...

...and then I had what must be the techie equivalent of a war flashback.
You see, Hitachi HGST used to be the storage division at IBM, and those guys gave us.
The DeathDeskstar 75GXP!

5 platters totalling 75GB in the top model! made of glass! cheap to buy! fastest (or near enough) desktop drive available! ultra-reli... oh wait.

Not that I'm saying that the 7K1000 won't be reliable, statistically it's likely that there will be occasional lemons but most will be absolutely fine. But we geeks are a fickle bunch, and the experience of all but one (I stopped counting the number of dead ones somewhere around 30) of the 75GXP's I've personally encountered.. ever... dropping dead in exactly the same way, has.. what's the phrase, scarred me for life enhanced my caution levels towards anything else from the same stable, am I being illogical? probably, unreasonable? certainly! but THIS sound is etched into my mind, I awaken in a cold sweat some, nay, most nights, at the notion of hearing it live and echoing throughout the room once again.

...And I'm just not sure I could bear it if it were 22x the quantity of data going up in smoke.

But onward! To actually having a point to this entry, exactly where is the boundary line between "I had a bad experience with this product and I'll go elsewhere for the replacement" and unreasonable grudge holding because of a lemon product?
