New client with TrueNAS 3.0 XL+ that has 8 bays. Does anyone know if Samsung 870 QVO 8TB SATA SSD drives witll perform and pass the smart test. (The website indicates only Micron).
It’s possible that only Micron was tested/validated and that others work just fine. I haven’t heard anyone complain that Samsung drives don’t provide SMART data, but I’ll defer that to others. I have no issue getting SMART from Intel Optane and Toshiba flash.
What’s the use-case for this storage and your planned vdev layout? I had used consumer-grade (admittedly cheap) QLC drives in a pool before for somewhat write-heavy ‘apps’ storage and burned through their endurance in ~6 months. By time I replaced them with Optane and lightly-used enterprise flash, they were dying off as quickly as I could replace them with the better drives 
I may have inadvertently caused some write amplification somewhere, and Samsung may have more durable QLC, but it soured me on cheap flash when it wasn’t a pool for primarily read activity.
Those are okay for bulk storage that rarely get written to, but terrible if you’re going to use it for block-based storage that requires frequent sync writes (ie. VM’s, databases). Not sure about those particular ones, but other cheap QLC consumer drives often could have even slower performance than high quality HDD’s once the write cache runs out.

Listen to @Whattteva , they speak sense.
QLC: The TBW will be lower, whatever you’re saving here is gone when these drives fail early. Also QLC writes slower than TLC.
DRAMless: Crimps your write performance even further.
Look for drives that use TLC Flash and have a DRAM buffer. They don’t cost a ton more, but give you good longevity and predictable performance.
