26TB drive for $250

I'm curious on why? I've been running desktop, and cheap, disks in my ZFS pool for over a decade now. Outside of normal failures from things being used beyond their design, they've been fine - and ZFS buys you a lot of leeway on a failure, too. I run raidz2 on each vdev, similar to RAID6, so I could lose two disks in each vdev, meaning if the "right" disks failed, I could lose 10 disks total without any data loss.

I've not had good experiences with desktop class drives in general versus enterprise drives. It's night and day.

On mine? It depends on which vdev has a failure. My tiny vdevs have 8TB drives, a resilver takes just about 12 hours on it. The 16TB based vdevs take somewhere around 18-20 hours. I haven't yet had to resilver with the 26TB drives, but, I'm expecting those to be somewhere around 30hr mark, give or take.
I could actually make improvements to my system to make that faster, but, I have never lost more than 1 disk at a time, so it's never been a priority for me to see how fast I could make it go. I don't let it slam the disks or backplane during resilvering, cos I still need the array to be as performant as possible, so resilvering basically gets only headroom I/O, as one example.

I've resilvered two 26TB barracuda's in my QNAP running QuTS and it's been over 48 hours for each to complete. I've got a mixture of 24TB and 26TB Exos and Barracudas in it now and the Exos are noticeably faster on the resilvers. It just depended on what was cheaper as I replaced things as to what drive I ended up with in that slot.

28TB is now $299.99 this morning at Seagate's site. Really debating do I pull the trigger on 8 of these drives for my NAS or not. lol

I wish the 10% coupon welcome discount still worked. Would be a nice chunk off. Probably just wait until Black Friday I suppose.

I'm guessing this is dead or I need coffee as I'm not seeing this on their site?

Yeah a QNAP isn't exactly known for high throughput and computational prowess :D I'm fairly certain a resilver will be 30 hours or less with mine. In fact, I may shuck my "spare" drive and shove it in there to see in a couple weekends from now. Right now I'm balancing all the data across the vdevs, which I have very tight cap on how much throughput I allow, so that'll day quite a few days to complete. After that I can test a resilver.

That's why I use 12TB disks, I'm already terrified of rebuild time with these.

Not just the rebuild time, but with the areal densities so high and the chance of an error still nearly the same from when drives had far less sectors, the changes of a flipped bit and a corrupt sector on a rebuild is a real issue. The only raid I ever use is RAID0+1 (or is it 1+0?) if at all, and that's just for speed that a single SSD can do instead.

I think it was for just 1 day, I ordered one and received it 2 days later (yesterday). Currently backing up most of my NAS now to it as I am building a new Truenas box (bought a ugreen 8 bay nas). I currently have an Epyc server I built 3 or 4 years ago with 256gb ddr4 ecc memory on a supermicro server board running Proxmox and have Truenas in a vm which works okay, although performance is not nearly as good as it should be for some reason, has to be a config issue in Proxmox or passthrough of the sas controller or something (it is passed through though and has 6 16tb wd gold enterprise drives on it), going to redo that entire server once I have the new Truenas server up and running.

This one running QuTS has a Xeon D-1622 with 16GB of ram, the main one running the non-ZFS QTS has a Ryzen 5 1600, both decent enough to serve up bits at 10GbE speeds.
