Samsung PM9A3 1.92TB M.2 PCIe 4.0 NVMe SSD

The Samsung PM9A3 is a high-capacity solid-state drive engineered specifically for server and data center environments. Utilizing the PCIe 4.0 x4 interface, this M.2 22110 form factor drive delivers high sequential throughput, reaching 6800 MB/s for reads and 4000 MB/s for writes. This performance is supported by strong random access capabilities, achieving up to 850,000 read IOPS. The combination of NVMe 1.4 support and the Samsung Elpis controller ensures consistent performance and low latency essential for transactional databases and virtualized infrastructure.

Designed for continuous operation, the PM9A3 features a high Mean Time Between Failures (MTBF) of 2,000,000 hours and is rated for 1 Drive Write Per Day (DWPD). Data integrity is maintained via comprehensive ECC (Error Correction Code) and end-to-end data protection mechanisms. The drive also supports TCG Opal and 256-bit AES-XTS hardware encryption, meeting stringent security requirements for sensitive data storage. Power efficiency is managed through low average power consumption (8W) and DEVSLP support, facilitating efficient integration into dense, multi-drive systems.
