I am running TrueNAS Scale 24.04.2.5. I have 2 zpools, a 2-vdev raidz2 of 12 spinning drives, and a newer pool of 6 2TB SSD’s, intended to run some vm’s off of. These were not the finest SSD’s, but my environment is not so critical that I needed expensive drives, I got mid-tier Amazon deals, and I understood the risks. This was fine for about a month, but the ssd’s began showing errors (initially within fault tolerance). I replaced one, but then errors started showing on the other drives, and as a precaution I moved all storage off of that pool. This was prudent, as it very quickly catastrophically failed and the pool and data would have been lost.
I completed a single drive replacement, and put the drive into an external enclosure for analysis…and the drive tested fine. No smart errors, wiped it, and it’s seemingly good as new. Meanwhile, the rest of the pool looks like this:
And the only fine drive is the one I replaced. Looking at the drive with the jillion errors, I put in a smart test, and got the following results:

I see several errors in there, but the disk shows “4” errors which is a far cry from Truenas’ console reading of 150k.
Can someone help explain what the “Error” count is in the above screen, and how it translates to actual failing drives? I’m taking this pool out and figuring out how to fund ordering better drives, but I’m confused by the disconnect between smart and the errors displayed.
