Product Specifications

PCIe Gen4 Performance

The Samsung PM9A3 3.84TB PCIe 4.0 U.2 NVMe SSD is optimized for PCIe Gen4 enterprise server platforms.

With sequential read speeds of up to 6,900 MB/s and sequential write speeds of up to 4,100 MB/s, it provides substantially higher throughput than traditional SATA SSDs and earlier PCIe storage generations.

Random read performance reaching up to approximately 1,000,000 IOPS also makes the drive suitable for workloads involving large numbers of concurrent storage operations.

AI Server and Data Center Applications

Typical applications include:

• AI and machine learning servers

• GPU server local storage

• Enterprise databases

• Cloud computing platforms

• Virtualization environments

• Software-defined storage

• Content delivery infrastructure
