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.
Just rebuilt onto Ceph and it’s a game changer. Drive fails? Who cares, replace it with a bigger drive and go about your day. If total drive count is large enough, and depends if using EC or replication, it could mean pulling data from tons of drives instead of a handful.
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.
You couldn’t afford this drive unless you are enterprise so there’s nothing to worry about. They don’t sell them by the 1. You have to buy enough for a rack at once.
They seem to be very hit and miss in that there are some models with very low failure rates, but then there are some with very high.
That said, the 36 TB drive is most definitely not meant to be used as a single drive without any redundancy. I have no idea what the big guys at Backblaze for an example, are doing, but I’d want to be able to lose two drives in an array before I lose all my shit. So RAID 6 for me. Still, I’d likely be going with smaller drives because however much a 36 TB drive costs, I don’t wanna feel like I’m spending 2x the cost of one of those just for redundancy lmao

Repeat after me: RAID is not a backup solution, RAID is a high-availability solution.
The point of RAID is not to safeguard your data, you need proper backups for that (3-2-1 rule of backups: 3 copies of the data on 2 different storage media, with 1 copy off-site). RAID will not protect your data from deletion from user error, malware, OS bugs, or anything like that.
The point of RAID is so everyone can keep working if there is a hardware failure. It’s there to prevent downtime.
It’s 36 TB drives. Most people are planning on keeping anything legal or self-produced there. It’s going to be pirated media and idk about you but I’m not uploading that to any cloud provider lmao
These are enterprise drives, they aren’t going to contain anything pirated. They are probably going to one of those cloud providers you don’t want to upload your data to.
I use mirrors, so RAID 1 right now and likely RAID 10 when I get more drives. That’s the safest IMO, since you don’t need the rest of the array to resilver your new drive, only the ones in its mirror pool, which reduces the likelihood of a cascading failure.
I would not risk 36TB of data on a single drive let alone a Seagate. Never had a good experience with them.
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.

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

The only thing I want is reasonably cheap 3.5" SSDs. Sata is fine just let me pay $500 for a 12TB SSD please.

100%. 36tb is peanuts for data centres

I can easily buy enterprise drives for home use. What are you on about?

Could you imagine the time it would take to resilver one drive… Crazy.
