In fact, after Samsung shamefully stopped installing 3D MLC chips in the Pro series, there is only one difference between "Pro" and "Evo" (both use 3D TLC) - the absence of a dram buffer in EVO, which greatly affects heavy mixed loads, and even when working as a system may have problems.
Let me remind you that Samsung once gave a 10-year warranty for the Pro series...
Let me also remind you that SSDs with MLC chips lose charge several times slower than 3D TLC chips and with wear of less than 10%, you can be sure that the data on the disk will be preserved for more than 10 years. And after 3 years, the drop in reading speed will be minimal, unlike 3D TLC, where reading speed can drop several times. And this was also the prerogative of the Pro series.
In fact, they are now selling the old "Evo" series with a dram buffer under "Pro".
I wouldn't risk with the 990 series and their trash controllers where they lose 6% health per month with average use. The Lexar NM790 is a bit more expensive but is a superior product in all aspects and there is no lottery to play with controllers. This 990 Pro would be pretty sweet under €/$100 as a scratch disk though.
Buyers all over the planet would benefit from the continued expansion of cheap Chinese YMTC chips like in middle of 2023, but it would not benefit the Western oligopoly of Samsung, WD, Hynix, Toshiba, Kioxia, etc.
The oligopoly won by banning the supply of ASML equipment to YMTC factories, and the buyers lost....
And the same Western system, screaming about the authorities "subsidizing" production in China, for some reason does not consider the anti-market mechanisms to support its producers for almost $300 billion to be the same brazen violation.
The entire planet saw the duplicity of Western morality and "principles." The main thing is money and selfish interest...
Thanks to a 42% discount, the 2 TB version of the popular Samsung 990 EVO PCIe 4.0 NVMe SSD is now down from $239.99 to $139.99 on Amazon. Although $10 higher than the lowest price ever, the current listing is quite attractive. Those happy with 1 TB can enjoy a 43% discount and snatch that version for $84.99 instead.
