Probably still with only 1 year warranty...

And if it breaks at 10 months and they take another 2 to send your replacement back, well, they no longer need to send one that actually works this time either
Whats the point when the prices for 4-8TB disks are stable the last 5 years? (I think that they are getting higher even...)
The point is the need for more and more data storage is never going to stop.
The point is that 8TB are too small, and not enough for my anime.

Yep. It's absurd. Who spends that much on a 4TB?
Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I've seen in this thread:

Does the increased density mean that the speed also goes up? It would be nice if a 7200 RPM drive could finally saturate SATA3 bandwidth.

I wonder why current consumer HDD's don't have NVME connectors on them. Like I know speeding up the bus isn't going to make the spinning rust access faster but the cache ram would probably benefit from not being capped at 550MBps
Question: Are failures due to issues on a specific platter? Meaning, could a ZRAID theoretically use specific platters as a way to replicate data and not require 140TB of resilvering on a failure?
@Fmstrat @veeesix Since there's two very diffrent questions there.. The first, "where do the failures happen?": anywhere. It could be the controller dying (in which case the platters themselves are fine if you replace the board, but otherwise the whole thing is toast). It could be the head breaking. It could be issues with a specific platter. It could be something that affects _all_ the platters (like dust getting inside the sealed area). So basically, it very much depends.
@Fmstrat @veeesix The second, could you do raid across specific platters - yes and no. The drive firmware specifically hides the details of the underlying platter layout. But if you targeted a specific model, you could probably hack something together that would do raid across the platters. But given the answer to the first question, why would you?

IIRC, HDDs have some reserved sectors in case some go bad. But in practice, once you start having faulty sectors it's usually a sign that the drive is dying and you should replace it ASAP.
I think if you know drive topology you can technically create partitions on platter level, but I don't really see a reason why you'd do it. If the drive is dying you need to resilver the entire drive's content to a new disk anyway.
Okay. I want total honesty here. How many of you could actually fill that thing up?
With useful stuff? Never. With random bullshit I think might be useful some day if only I find the time? Easy
... or be able to backup it?
No sweat, try mirroring a private tracker and you'll very quickly run out lol. You need a couple of petabytes worth.
The real problem is the price of HDDs not going down due to lower production in light of SSDs.
I fully expect WD to drop this as some stupidly expensive SAS drives that almost no consumer will buy. They should at least apply the dual heads for speed tech so we get faster HDDs for the same price.

Doesn't this sound awfully similar to the Mini disc technology? The discs were only writable when heated by a laser. They were pretty impressive for the time... But not very fast. Especially when writing.
I'd put this in a mirror configuration tbh.
