Samsung SSD 9100 PRO 1TB, PCIe 5.0x4 Review & Specifications

The Samsung SSD 9100 PRO 1TB, PCIe 5.0x4 by SAMSUNG is a NVMe solid-state drive (SSD) featuring 1000 GB of storage. It is built with TLC 236-layer NAND flash memory and utilizes a Samsung Presto (S4LY027) controller to manage data access, wear leveling, and overall performance. This model leverages the cutting-edge PCIe 5.0 x4 interface, delivering a theoretical maximum bandwidth of up to 32 GB/s. It also complies with the modern NVMe 2.0 specification, which introduces modular architecture, improved command sets, and support for Zoned Namespaces. The drive is available in a M.2 2280 form factor. Note that optimal performance requires a motherboard with PCIe 5.0 support; otherwise, the SSD will operate at the maximum speed allowed by your system configuration.

NVMe SSD Performance

Sequential read and write speeds reach 14700 MB/s and 13300 MB/s respectively, while random read/write performance delivers up to 1850k and 2600k IOPS. The drive offers an endurance rating of 600 TBW and is backed by a 5-year manufacturer warranty.

This SSD includes a dedicated 1024 MB DRAM cache module running at 4266 MHz. This discrete DRAM chip serves as a high-speed buffer between the controller and NAND flash, significantly reducing latency and improving random read/write performance. DRAM allows the controller to store the Flash Translation Layer (FTL), which is essential for efficient address mapping and wear leveling. Combined with a Dynamic and static SLC write cache, it offers excellent burst speeds and consistent performance under heavy workloads.

This SSD module delivers ultra high-end performance, reaching 93.0% of the maximum score in our synthetic benchmark—measured relative to the fastest NVMe SSD in our database. It is engineered for cutting-edge gaming rigs, advanced workstation environments, and high-frequency data pipelines such as 4K/8K video editing, real-time rendering, and scientific data processing.

Cost-Effectiveness

From a cost-per-storage perspective, this SSD offers below-average value at $250.0 per terabyte. The overall combined performance-to-price ratio, which evaluates both maximum performance and total storage capacity per dollar, is calculated at 55.8%. Based on this metric, the drive is a less favorable value in this category. However, with a high raw performance rating of 93.0%, it may still appeal to users who prioritize speed and responsiveness over cost or capacity. For budget-conscious users, more balanced alternatives may be preferable.
