The highest capacity SSDs are still just 1TB and offer 50 cents/GB, while these 5TB drives are under 5 cents/GB. If you need two-three drives for Raid1/5, these are the way to go, and keep a 120GB SSD for your OS/programs/cache

Very wrong phatboye. The only reason people still buy non-SSD drives is for mass-storage, back-ups, etc...If they make 10-15K rpm drives, nobody will care. In fact when SSDs came out the 10-15K drives died out first, only the slower/larger drives are surviving.

More than hot air and a good solution to the limitations of current magnetic storage technology.

Creating a sustainable vacuum would require much higher grade and pressure-resistant sealing technology, with arguably more cost.

Also with a vacuum the heat would not spread efficiently and damage will soon occur.

THe heads fly over the platter aerodynamically - this wouldn't work in vacuum.

I could imagine something like 1/10th of ambient pressure of much cheaper nitrogen as an alternative, though.

I remember a vacuum test of CDS drives back in the 70's. The heads actually flew higher because air was trapped between the heads and the disks probably because of molecular attraction.

The photo of the drive isn't the real thing. The "invention" is in the sealing process & the interconnection between the tub & the electronics outside the tub. VERY INTERESTING!
