Samsung 9100 Pro MZ-VAP4T0BW 4TB

The primary distinction between the Samsung 9100 Pro and the 990 PRO lies in their underlying interface technology, which translates directly into a significant performance gap. The 9100 Pro utilizes the newer PCIe Gen5 x4 NVMe interface, enabling dramatically faster sequential read and write speeds, reaching up to 14800 MB/s read and 13400 MB/s write. In contrast, the 990 PRO is limited to the PCIe Gen4 standard, maxing out at 7450 MB/s read and 6900 MB/s write. Random performance also favors the 9100 Pro, showing superior 4KB read and write operations. While both drives offer the same substantial 4TB capacity and a 5-year warranty, the 9100 Pro represents a considerable generational leap in throughput, making it the superior choice for users requiring the absolute fastest data transfer speeds available today.
