Is this Seagate Exos drive too good to be true?

It's just the cheapest type of drive there is. The use case is in large scale RAIDs where one disk failing isn't a big issue. They tend to have decent warranty but under heavy load they're not expected to last multiple years. Personally I use drives like this but I make sure to have them in a RAID and with backup, anything else would be foolish. Do also note that expensive NAS drives aren't guaranteed to last either so a RAID is always recommended.
To support this: Backblaze consistently reports much higher failure rates for Seagate drives than all others. I personally don't trust them. All my failed drives are Seagate, but that's anecdotal. https://www.backblaze.com/cloud-storage/resources/hard-drive-test-data https://www.backblaze.com/blog/backblaze-drive-stats-for-2022/ the by manufacturer graph.
That tracks with my experience as well. Literally every single Seagate drive I've owned has died, while I have decade old WDs that are still trucking along with zero errors. I decided a while back that I was never touching Seagate again.
For sure higher but still not high, we're talking single digit percentage failed drives per year with a massive sample size. TCO (total cost of ownership) might still come out ahead for Seagate being that they are many times quite a bit cheaper. Still drives failures are a part of the bargain when you're running your own NAS so plan for it no matter what drive you end up buying. Which means have cash on hand to buy a new one so you can get up to full integrity as fast as possible. (Best is of course to always have a spare on hand but that isn't feasible for a lot of us.).
Ok cool, I plan on using them in RAID Z1
Make that RAID Z2 my friend. One disk of redundancy is simply not enough. If a disk fails while resilvering, which can and does happen, then your entire array is lost.
Hard agree. Regret only using Z1 for my own NAS. Nothings gone wrong yet 🤞but we've had to replace all the drives once so far which has led to some buttock clenching.
When I upgrade, I will not be making the same mistake. (Instead I'll find shiny new mistakes to make)
This should be the community slogan
You must be running an icredible HA software stack for uptime increases so far behind the decimal to matter.
That was uncalled for.
