Does seem like a big deal.
Every day it adds one rack of storage.
It takes 2 or 3 yrs to fill a server building....
They just need 5 new buildings every 10yrs which is not a big deal.
At the same time disk space double every 1.5yrs.
Maybe new technologies allow 207 tera on single disk is possible in the future.
The good news is data bit can be made very small in HDD.
Now 1 pc of 3.5" HDD media can store up to 2TB of data.(Still the same size when first 3.5" HDD produced about 30++years ago)
HDD is going for next Gen soon called HAMR or MAMR. It depends which technology the market players want to adopt.
With RAID storage technology, you can also combine multiple harddisks into 1 drive.
