I assumed that these drives had the same controller chip and the same firmware base as the consumer samsung SSDs, but with higher quality nand and some firmware tweaks. It's very hard to find technical details about these enterprise drives on the internet (compared to the consumer drives).
I guess the smartctl command proves it, these enterprise samsung SSDs do not have queued trim enabled.
It would make sense for enterprise drives to be more conservative and lag on feature set. But it's very surprising that enterprise drives are corrupted by original un-queued trim, they're supposed to have more validation, and that's a very common feature.
