Samsung 990 PRO PCIe 4.0 NVMe M.2 SSD 1TB

The primary distinction between the Samsung 990 PRO 1TB and the 2TB model lies in storage capacity, which directly impacts suitability for different user needs. While both utilize the high-speed PCIe Gen4 x4 NVMe interface and share identical maximum sequential read/write speeds of 7450 MB/s and 6900 MB/s respectively, the larger 2TB drive offers double the total endurance with a TBW rating of 1200 compared to the 1TB's 600. Furthermore, the 2TB version boasts superior random performance, evidenced by a higher 4KB random read figure of 1,400,000 compared to 1,200,000 on the smaller capacity model. Both units share the same physical M.2 Type 2280 form factor and a 5-year manufacturer warranty. Ultimately, the 2TB variant is better suited for intensive workloads or users requiring significant space, while the 1TB serves as a strong, slightly more budget-conscious option for general use.
