The longer the time, the more likely the rebuild will fail.
That said, modern raid is much more robust against this kind of fault, but still: if you have one parity drive, one dead drive, and a raid rebuild, if you lose another drive you’re fucked.
I remember first hearing about 1TB and thinking (who needs that much storage?) wasn’t an IT person then just a regular nerd but am now and it took me a while to ever fill up my first 1TB HDD (steam folder) now I have a 2TB NVME in my desktop and a 4TB NVME in my server (for my Linux ISOs ;))
It’s so consistent it has a name:
Moore’s law is the observation that the number of transistors in an integrated circuit (IC) doubles about every two years.

Quick note, HDD storage is not using transistors to store the data, so is not really directly related to Moore’s law. SSDs do use transistors/nano structures (NAND) for storage and it’s storage capacity is more related to Moore’s law.
Ignoring the Seagate part, which makes sense… Is there a reason with 36TB?
I recall IT people losing their minds when we hit the 1TB, when the average hard drive was like 80GB.
So this growth seems right.
It’s raid rebuild times.
The bigger the drive, the longer the time.

1TB? I remember when my first computer had a state of the art 200MB hard drive.

Remembering when Zip drives sounded so big!

I heard that we were at the theoretical limit but apparently there’s been a break through: https://phys.org/news/2020-09-bits-atom.html
