What drives do you have exactly? I have 7x6TB WD Red Pro drives in raidz2 and I can do a scrub less than 24 hours.
I have 2*12TB whitelabel WD drives (harvested from external drives but Datacenter drives accourding to the SN) and one 16 TB Toshiba white-label (purchased directly also meant for datacenters) in a raidz1.
How full is your pool? I have about 2/3rds full which impacts scrubbing I think.
I also frequently access the pool which delays scrubbing. -
That's a use-case for a fuckton of total capacity, but not necessarily a fuckton of per-drive capacity. I think what the grandparent comment is really trying to say is that the capacity has so vastly outstripped mechanical-disk data transfer speed that it's hard to actually make use of it all.
For example, let's say you have these running in a RAID 5 array, and one of the drives fails and you have to swap it out. At 190MB/s max sustained transfer rate (figure for a 28TB Seagate Exos; I assume this new one is similar), you're talking about over two days just to copy over the parity information and get the array out of degraded mode! At some point these big drives stop being suitable for that use-case just because the vulnerability window is so large that the risk of a second drive failure causing data loss is too great.
Thats exactly what I wanted to say, yes :D.

What is the usecase for drives that large?
I 'only' have 12Tb drives and yet my zfs-pool already needs ~two weeks to scrub it all. With something like this it would literally not be done before the next scheduled scrub.
Jesus, my pool takes a little over a day, but I’ve only got around 100 tb how big is your pool?

my qbittorrent is gonna love that

The pool is about 20 usable TB.

Sounds like something is wrong with your setup. I have 20TB drives (x8, raid 6, 70+TB in use) .... scrubbing takes less than 3 days.

finally i'll be able to self-host one piece streaming

Data centers???

Two weeks to scrub the pool sounds like something is wrong tbh.

Finally, a hard drive which can store more than a dozen modern AAA games

Something is very wrong if it's taking 2 weeks to scrub that.

I get it. But the moment we invoke RAID, or ZFS, we are outside what standard consumers will ever interact with, and therefore into business use cases. Remember, even simple homelab use cases involving docker are well past what the bulk of the world understands.

High capacity storage pools for enterprises.
Space is at a premium. Saving space should/could equal to better pricing/availability.Not necessarily.
The trouble with spinning platters this big is that if a drive fails, it will take a long time to rebuild the array after shoving a new one in there. Sysadmins will be nervous about another failure taking out the whole array until that process is complete, and that can take days. There was some debate a while back on if the industry even wanted spinning platters >20TB. Some are willing to give up density if it means less worry.
I guess Seagate decided to go ahead, anyway, but the industry may be reluctant to buy this.
-
well, it depends. if they were dropped just because they are smr and were writing slowly, I think they are fine. but otherwise...
what array system do you use? some raid software, or zfs?
Windows Server storage solutions. I took them out of the array and they still weren't recognized in Disk Management so I assume they're shot. It was just weird having 2 fail the same way.

I would assume with arrays they will use a different way to calculate parity or have higher redundancy to compensate the risk.

Can't wait to see this bad boy on serverpartdeals in a couple years if I'm still alive

This hard drive is so big, that astronomers thought it was a planet.
This hard drive is so big, it's got its own area code

if I'm still alive
That goes without saying, unless you anticipate something. Do you?

A ZFS Scrub validates all the data in a pool and corrects any errors.
I'm not in the know of having your own personal data centers so I have no idea. ... But how often is this necessary? Does accessing your own data on your hard drive require a scrub? I just have a 2tb on my home pc. Is the equivalent of a scrub like a disk clean up?

Hello!
