Man, I remember when someone on reddit got mad upvotes for saying “5tb hard drives don’t exist” in response to me, as the external 5tb hdd I was using sat 2ft away from me.
And here we are looking at the [BRAND] advertisement for 120TB drives.
I remember when I got my forst 120gb drive. I happily installed it on my win 2k and… bios didn’t like it, OS didn’t like it and read its capacity wrong. I forget if I used windows or linux but after I cut the drive into 2x60gb it worked great
I’m pretty sure they were referring to how the more common sizes are 1, 2, 4, 8, 10, 12 TB and so on. 6 is semi-common. 5 is relatively rare, so they probably didn’t realize they exist.
I own a couple of 5TB drives. At the time when 8TB and above were rare and expensive, it wasn’t that strange.
Finally, all of my homework on one drive.
I remember reading an interesting take on the 20TB drives when they came out - the impact of drive failure skyrockets with large density drives.
Back with 2TB drives, you could fit 60-70 Blu-ray rips. If that drive dies (without backups/RAID), you’ll be hurting but not as bad as if you have a filled 20TB with 600-700 rips. Plus, even with RAID, the rebuild time increases with density, and for 20TB drives you could be waiting a week for rebuild.
I like the idea of higher density drives, but in my opinion they only really make sense in large drive arrays where you can spread the data over dozens and dozens of replicated drives.

Luckily the ones that are considering buying this have that or something similar and/or extensive backups.
The info graphic suggests that they use the different cooling rate of the first and second layer to lock in the applied magnetic field of heat assisted magnetic recording.
They beat both layers
They apply a magnetic field to save a “1” bit
Both layers are magnetized to a “1” bit
The first layer cools down and locks that bit into place permanently.
They apply the magnetic field to save a “0” bit
While the second layer is still hot and accepts the “0” orientation of the magnetic field, the first layer is already too cold and will not change its magnetization.
The second layer cools down and locks that bit into place.
Neat!
