Score: 80/100
Kingston NV3 1TB
Score: 81/100Rankings

The Kingston NV3 1TB M.2 SSD delivers PCIe 4.0 speeds at a budget-friendly price, using a DRAM-less architecture that keeps power low and size minimal. While it offers impressive sequential performance, its consistency and long-term reliability may lag behind higher-end models.

The Silicon Power UD90 1TB PCIe 4.0 SSD delivers flagship-class sequential speeds at a budget price, but its DRAM-less design and lack of a heatsink lead to thermal concerns and mixed reliability reports.
