Heh, and they can shatter. Had a customer bring in a laptop after they dropped it and said the hard drive wasn't detected.

Taking the hard drive out and rotating it made the noise of a thousand scurrying roaches.

2.5 drives have less platters which are also smaller.

I hope everything goes well and we'll see 100TB drives.

I'm not sure whether the smaller size is an asset or liability here. There's likely some tradeoffs for manufacturing tolerances and/or thermals. (physics people speak up?)
