Let’s say you have a good 20tb drive and it can transfer files at 200MB/s. To fill that drive, it’ll take 1 day and 8 hours of continuous transfer. If it’s failing, and you’re trying to get as much off of it you’re screwed.

this is kind of why we have RAID, but arguably, you should literally just not be using RAID as a backup. Failing drives should be prepped for in advance, rather than dealt with in real time at the 20+TB scale.

The primary advantage to such dense HDDs is price, and power efficiency.

Also there’s this thing that the higher capacity a storage device gets, the more valueable the data stored on it becomes, not directly because it’s high capacity, but because it’s more trusted by the user.

also im not sure i agree with the phrasing here, the drive does become "more important" but that's because it stores more data, there is literally more for you to lose in the event it gets destroyed. You should trust nothing ever, yourself included.
