Great fast memory. Programs, games, anything launches instantly. Compared to the 970 EVO, the difference is not very noticeable, but next to an HDD, it's like comparing a sports car with a compact car. The attached test screenshots show it falling slightly short of the stated claims, but I think that's due to my PC configuration. Speed, reliability The sudden chip crisis that has caused the price to skyrocket  Volodimir : use Samsung MZ-V9S2T0BW less than month |
