Well I got some info about it if anyone’s interested.

“Originally was SM2258 (w/DRAM) + TLC, they may have moved to the SM2259 or equivalent now (they still list DRAM). Probably newer TLC. Can’t rule out QLC (“3D NAND”) but the performance and TBW specs look pretty good (0.3 DWPD is typical for TLC).”

Yeah? For me it’s great, but I think americans and europians can find lower prices.
You should check out camelcamelcamel for price changes on Amazon. Samsung’s 870 EVO 4tb ssd was recently sold at 170$

About 190$
I’ve seen other ssds in that price, but I usually need to add tax + shipping to that.
