DISKDRILL FAILED MANUAL

I just wanted to note that I've been having a similar experience. Could this negatively affect the life of the SSD? I moved the System Dataset to the SSD to reduce the noise coming from the NAS in the first month or so. Therefore, I would like to ask what is in your opinion the best choice for the SSDs? I have seen in this post that the Kingston A400 is not the best choice for a boot pool.

DISKDRILL FAILED MANUAL

Essentially, the same things happen as described in this post (errors -> DEGRADED status -> zpool clear -> scrub-> manual tests pass -> then during the scheduled SMART tests, the tests fail -> errors -> boot is DEGRADED -< repeat). The funny thing is that about 90% of the time, the SMART tests pass, especially if I start them by hand but they usually fail during the scheduled tests when the NAS has been running for a while. For a while, the system ran perfectly, passing short and long SMART tests, but about 1 month later, the errors showed up again. I was dumb enough to replace it with a new A400 once again. One of the SSDs failed spectacularly with 1000+ write errors and a ton of read errors, which totally bricked the SSD (the other SSD that was in the same mirror reported 1 TB of data written at this point on Disk Drill). However, errors still happen to this day. Then, I replaced the data cables, same thing, and then I replaced the power cables. Then, I changed SATA ports, but the errors kept happening. The first write error happened roughly 1 month after installation, and then happened every single time after the SMART tests have been run on each Sunday (most of them happened when the catalog sync took place). I use 2 Kingston A400 250GB SSDs in a mirror for the boot pool of my TrueNas Scale installation.

I have seen some recommendations for the Intel D3-S4520, and the Samsung 860 and 870, with some counterarguments for the latter two as well. In your opinion, what is the best SSD for a boot pool that is not awfully expensive? This is essentially a home NAS with some more important work-related documents stored on it as well. However, I am a bit lost at which SSD to actually choose in order to not run into these exact same errors & problems.

After trying out many things (see more details below), I decided on using other SSDs. However, the SSDs that I use for my boot pool have been driving me nuts with some occasional read/write errors, which renders the pool DEGRADED. I have built my first TrueNas, which I have been enjoying for the past 5 months or so.
