Hello everyone,
I have built my first TrueNas, which I have been enjoying for the past 5 months or so. 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. After trying out many things (see more details below), I decided on using other SSDs. However, I am a bit lost at which SSD to actually choose in order to not run into these exact same errors & problems.
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. 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.
A little more detail:
I use 2 Kingston A400 250GB SSDs in a mirror for the boot pool of my TrueNas Scale installation. 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). Then, I changed SATA ports, but the errors kept happening. Then, I replaced the data cables, same thing, and then I replaced the power cables. However, errors still happen to this day. 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). I was dumb enough to replace it with a new A400 once again. For a while, the system ran perfectly, passing short and long SMART tests, but about 1 month later, the errors showed up again. 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. 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). I have seen in this post that the Kingston A400 is not the best choice for a boot pool. Therefore, I would like to ask what is in your opinion the best choice for the SSDs?
Another detail:
I moved the System Dataset to the SSD to reduce the noise coming from the NAS in the first month or so. Could this negatively affect the life of the SSD?
Thank you in advance!
