UPDATE: In November of 2020 I ended up buying 8x 8TB Western Digital Datacenter drives and an LSI 9207-8i HBA and it’s been working flawlessly since (raidz2). Only complaint is it consumes a fair amount more power; 80 W before, 150 W now, however it’s a fair trade off for double the redundancy and more than double the transfer speeds, ZFS scrubs are also now massively faster compared to chipset SATA however I did upgrade the dataset to the new zfs version, switch from LUKS to native encryption and tweak a lot of tunables when migrating. In the video I say that the dataset had underground a read/write endurance of 5.3 PiB, this is incorrect as I thought because this is a 4K device the number of blocks read/write would be reported in 4096 b blocks, however I have since learnt that most ATA devices will report this in 512 b blocks regardless of their real block size, the correct number is 1.8 PiB (0.6 PiB/drive, 0.2 PiB/drive/year) (still a lot more than the warranty covers) however this means the WD Gold drives I’ve bought have sufficient warranty (0.55 PiB/drive/year for 5 years).

Great video! Exactly what I wanted to learn, including the emotions 🙂

I bought two iron wolf HDDs earlier this year. Hardly used. Having similar errors on one disks, with similar rates of read/write errors that you have with smart disk report. What are your badblocks options?

Here's the commands I used the most for badblocks: github.com/WizardTim/cheatsheets/blob/master/badblocks.md If you're getting similar SMART errors to me I would recommend you just return the drive and get a replacement or refund. The Seagate IronWolf drives come with 3 limited warranties (180 TB/year), depending on what country you're in, getting a replacement/refund is probably the easiest and safest option.

Can you swap in any 7200rpm drive? Or does it limit you to being the same one.

I can swap in any hard drive that is exactly the same formatted size (or larger) including 5400 rpm drives but the performance I get will be that of the slowest drive plus there’s also annoyances with the sector sizes, cache size and access time which makes me hesitant to spend money on a drive to make a pool that’s already towards the end of its life run slower and be more annoying to configure. Since making this video I think I’ve settled on buying some Western Digital Gold enterprise drives, a proper PCIe HBA and possibly an L2ARC/ZIL SDD but it’s going to be a very expensive purchase so I’m going to think about it for a while.

Thanks for that. I'll definitely RMA them. I bought them from PBTech, so that'll be sweet.

@@WizardTim This is why you normally take a partition so a different drive of almost the same size will always have enough capacity. And if it's roughly the same in access time and throughput, it doesn't matter at all. Just make sure you have an ashift of 12 on your pool and your drives have properly aligned partitions.

I've run years, and still do on Toshiba dt01aca200 consumer drives. The thing that was different with these ones, is that they have a configurable TLER. I'm also running in triple mirror, because I'm a drunken moron. It saved me a couple of times too, when I pulled the wrong drive, or forgot to put some back when rebooting the thing. Oh well.
