It isn't as much as you think, high resolution, high bitrate video files are pretty large.
high resolution, high bitrate video files are pretty large.
Can it actually transfer data fast enough to save or play them back in real-time, though?

So if you have been around long enough you might remember the Hitachi (IBM) deathstars https://wizardprang.wordpress.com/2013/10/14/the-last-deathstar/
I see Hitachi and think no fucking way, where as Seagate I used to see as an always yes. Now I just stick the disks in a zfs array and call it done
What I'm really waiting for is large capacity ssds with sata.
Yes I remeber Deathstars. However, these past years I perfunctorly peruse Backblaze's yearly drive failure reports, and have noticed a trend, which is that most drives are fine, but every year there are a few that stand out as very bad, and they usually Seagate/WDC.
Exceptions yada, yada

As mentioned by another user, all drives fail, it's a matter of when, not if. Which is why you should always use RAID arrangement with at least one redundant drive and/or have full backups.
Ultimately, it's a money game. If you save 30% on a recertified drive and it has 20% less total life than a new one, you're winning.
Here's where I got some.
Manufacturer Recertified Drives | Enterprise Grade
Manufacturer Recertified enterprise drives work and look like new. Rebuilt by the manufacturer and quality tested to ensure they function as new, our recertified drives save on cost. Shop now!
ServerPartDeals.com (serverpartdeals.com)
I looked around a bit, and either search engines suck nowadays (possibly true regardless) or there are no independent studies comparing certified and new drives.
All you get mostly opinion pieces or promises by resellers that actually, their products are good. Clearly no conflict of interest there. /s
The best I could find was this, but that's not amazing either.
What I do is look at backblaze's drive stats for their new drives, find a model that has a good amount of data and low failure rate, then get a recertified one and hope their recertification process is good and I don't get a lemon.
And usually by the time they break they have been obsolete anyways, at least for 24/7 use in a NAS where storage density and energy efficiency are a big concern. So you would have replaced most of them long before they break, even with recertified drives

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.
High capacity storage pools for enterprises.
Space is at a premium. Saving space should/could equal to better pricing/availability. -
I too, am old.
I'm older than that but didn't want to self report. the first hard disk i remember my father buying was 40mb.
-
there was a time i asked this question about 500 megabytes
I am not questioning the need for more storage but the need dor more storage without increased speeds.

no thanks Seagate. the trauma of losing my data because of a botched firmware with a ticking time bomb kinda put me off your products for life.
see you in hell.
Some of Seagate's drives have terrible scores on things like Blackblaze. They are probably the worst brand, but also generally the cheapest.
I have been running a raid of old Seagate barracuda's for years at things point, including a lot of boot cycles and me forcing the system off because Truenas has issues or whatnot and for some fucking reason they won't die.
I have had a WD green SSD that I use for Truenas boot die, I had some WD external drive have its controller die (the drive inside still work) and I had some crappy WD mismatched drives in a raid 0 for my Linux ISO's and those failed as well.
Whenever the Seagate start to die, I guess ill be replacing them with Toshiba's unless somebody has another suggestion.

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.

Jesus, my pool takes a little over a day, but I’ve only got around 100 tb how big is your pool?

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.

I also frequently access the pool which delays scrubbing.It's like 90% full, scrubbing my pool is always super fast.
Two weeks to scrub the pool sounds like something is wrong tbh.

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.

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.
