The Samsung 990 PRO is a PCIe Gen4 x4 NVMe 2.0 internal SSD built on Samsung's in-house controller and V-NAND. The 4TB version is the largest in the line, aimed at people who need fast storage for large game libraries, video editing and heavy multitasking. It is one of the fastest Gen4 drives available, with sequential reads near the top of the Gen4 class and strong random performance. Rivals like the WD Black SN850X and Crucial T500 are close in real-world use, so the 990 PRO stands out mainly on sustained speed, power efficiency and Samsung's Magician software.
