In all seriousness, though... I get the concept (as with the nitrogen-filled tires), I'm sure the benefits are legit, but wonder if it's really worth the hoopla, OR the additional cost. Granted, I don't know what kind of premium one pays on these drives over a similar non-He 6TB model (if they exist)...
I know with the tire/nitrogen thing, it's a good IDEA, I understand all the ideas behind it (less prone to expansion when heated, larger molecules won't leech through the tire as readily), but the fact is, the regular air being compressed and pumped into the tires is already 79% nitrogen.
I dunno, it reminds me a bit of a couple of ads I saw once in Car Audio Magazine many many years ago... one was an amplifier touting the benefits of their "SCAT" design - SCAT standing for Solid Core Acoustic Technology, essentially meaning they used solid rather than stranded wire for the internal wiring (with the requisite in-depth explanations of how this made things better); the other was for a CD head unit that made a big deal of the fact they used an optocoupler connection between the CD pickup and the rest of the deck's electronics... besides the noise isolation, they claimed better sound because the optocouplers moved signal "at the speed of light - that's fast!" (yes, I remember it used that exact wording) - uhh, last I checked, electricity moved pretty near the speed of light as well, close enough that any differences would be irrelevant over the few millimeters involved.
*sigh* Yay for marketing...
