So 7 platters instead of the usual 3/4 or 5 tops? Man that thing is going to make a lot of noise and vibrate a lot!

Funny how WD announced a 5.5TB HGST Helium drive and HGST market it as 6TB...

I'm just wondering, if having 1/7th the air density is the reason for this being possible, why don't they have drives in a completely evacuated chamber? Probably more expensive than it's worth... but I'm just curious.

You need air to keep the head from crashing into the disk.

I guess the case of the drive would have to be fortified to prevent the drive from imploding if there was vacuum inside, whereas helium can be kept at normal atmospheric pressure. It could also pose a risk if damaged.

I already answered. It has nothing to do with implosions, but with the need for air so that the head doesn't touch the disk: http://www.instantfundas.com/2010/02/interesting-hard-drive-facts-you.html (Read the last part)

Ah so in other words, they'd have to design the heads differently. At least, that's what I get out of the article. Thanks for that by the way, that was a good read.
