SSD disk Samsung PM9D3a 3.84 TB 2.5 inch NVMe PCIe 5.0 — 12,000 MB/s read, 6,000 MB/s write

The Samsung PM9D3a SSD is a high-capacity 3.84 TB solid-state drive in a 2.5" form factor that uses the PCI Express 5.0 NVMe interface. Engineered for server and data-center environments, this drive delivers very high sequential read speeds up to 12000 MB/s and write speeds up to 6000 MB/s, combining large storage density with low-latency NVMe performance in a compact 2.5" package.

Advantages

The PM9D3a provides a combination of large usable capacity and the bandwidth of PCIe 5.0 NVMe, enabling faster data transfer and shorter I/O completion times for demanding workloads. The 2.5" mechanical format simplifies integration into server trays and storage arrays, while the drive’s architecture is optimized for sustained throughput and consistent performance under concurrent access. Built with enterprise-grade design considerations, it supports workloads that require high read/write bandwidth and efficient storage consolidation.

Suitable for

• High-performance database storage and transaction processing
• Virtualization hosts and hyperconverged infrastructure
• Analytics, AI/ML training data sets and inference workloads
• High-throughput file servers and media streaming
• Storage tiering in enterprise storage arrays

Key specifications

• Capacity: 3.84 TB (3840 GB)
• Form factor: 2.5 inch
• Interface: PCI Express 5.0 with NVMe protocol
• Maximum sequential read speed: up to 12000 MB/s
• Maximum sequential write speed: up to 6000 MB/s

How to use

Install the SSD into a compatible NVMe-capable 2.5" slot or drive bay that supports PCIe 5.0, following the server or chassis manufacturer’s installation instructions. Ensure the host system firmware and operating system are updated to support PCIe 5.0 and NVMe drivers. After physical installation, initialize and format the drive as required by your storage configuration, and integrate it into the appropriate RAID, logical volume, or file system setup. Monitor drive health and performance using vendor-provided tools or standard S.M.A.R.T. and NVMe management utilities.

Recommendations

For consistent performance in multi-tenant and heavy I/O environments, use the PM9D3a in systems with adequate cooling and stable power delivery. Follow enterprise storage best practices such as firmware maintenance, regular health checks, and workload-aware provisioning to maximize longevity and predictable performance.
