Wait, "950" might be confusing because some SSD models have version numbers too, like the Samsung 850 EVO or 960 EVO. But the user wrote "ssis950"—maybe a typo? Maybe it's the Samsung 950 or 850 EVO? Also, "4k+verified" might be a requirement in their system or application. I should check if there are specific use cases where 4K performance is critical, like servers, databases, or gaming.
