Samsung PM9A3 Datasheet and Technical Specifications

The Samsung PM9A3 is an enterprise-grade NVMe SSD designed primarily for data centers, servers, cloud computing, transactional databases, and other demanding workloads. It uses a PCIe 4.0 x4 interface with NVMe 1.4, providing significantly higher bandwidth than older PCIe 3.0 enterprise SSDs. Samsung designed this enterprise SSD for reliable 24/7 operation while balancing performance, power efficiency, endurance, and data security.

The Samsung V-NAND PM9A3 is available in several form factors, including 2.5-inch U.2, E1.S, and M.2, depending on the specific model. U.2 versions are available in capacities ranging from 960GB to 7.68TB, while other form factors have different capacity ranges. The U.2 version measures approximately 100.2 × 69.85 × 7 mm, making it suitable for enterprise server platforms designed for 2.5-inch U.2 drives. Performance varies according to capacity and form factor. For the U.2 models, Samsung specifies sequential read speeds of up to approximately 6,900 MB/s and sequential write speeds of up to 4,100 MB/s on higher-capacity versions. Random performance can reach around 1.0–1.1 million IOPS for read operations and up to 200,000 IOPS for random writes. The 960GB U.2 model is rated lower, at up to 6,500 MB/s sequential read, 1,500 MB/s sequential write, 580K random-read IOPS, and 70K random-write IOPS.

The drive uses Samsung V-NAND TLC flash memory and a Samsung in-house controller. Enterprise features include power-loss protection (PLP), which helps protect data in the event of an unexpected power interruption, as well as end-to-end data-path protection. Samsung also supports AES 256-bit hardware encryption and enterprise security standards such as TCG/Opal on supported versions. For reliability, the Samsung PM9A3 is rated at approximately 2 million hours MTBF and offers 1.0 drive write per day (DWPD) for five years on the relevant enterprise configurations.
