Micron 9550 PRO NVMe SSD (U.2 15.36TB)

The Micron 9550 PRO is a high-capacity enterprise NVMe SSD built on PCIe Gen5 x4 (NVMe 2.0) technology, housed in the industry-standard U.2 2.5-inch form factor. Leveraging Micron's advanced 232-layer TLC NAND and a purpose-built Gen5 controller, it achieves sequential read throughput of up to 14 GB/s and sequential write throughput exceeding 7 GB/s — nearly doubling the bandwidth envelope of its PCIe Gen4 predecessors. The drive is optimized for the latency-sensitive, bandwidth-saturating demands of modern AI infrastructure including large-scale model training checkpointing, high-throughput inference serving, and GPU-direct storage pipelines where NVMe over PCIe feeds accelerators at line rate.

At 15.36TB raw capacity in a single 2.5-inch U.2 bay, the 9550 PRO enables extreme storage density consolidation in AI servers, hyperscale nodes, and GPU-rich platforms without sacrificing random I/O performance. The drive delivers up to 3.0 million random read IOPS and up to 700,000 random write IOPS, supporting the mixed queue-depth profiles typical of vector database queries, embedding lookups, and parallel data loader pipelines used in LLM pre-training clusters. Power delivery is rated for the E3.S/U.2 ecosystem with intelligent dynamic power management that throttles consumption under light load while sustaining full performance under sustained queue depths.

The Micron 9550 PRO incorporates enterprise-grade reliability features including end-to-end data path protection, power-loss protection (PLP) capacitors, and a 1 DWPD endurance rating calibrated for predominantly read-intensive AI and analytics workloads. Secure cryptographic erase and AES-256 self-encrypting drive (SED) capability address data-at-rest compliance requirements in regulated enterprise and government environments. The drive supports Zoned Namespaces (ZNS) readiness, NVMe Management Interface (NVMe-MI) for out-of-band fleet telemetry, and Sanitize Instant Erase (SIE) for rapid decommissioning.

Ideal for

• AI/ML training checkpoint storage: High-capacity, high-bandwidth local NVMe scratch space for frequent model checkpoint writes in GPU clusters running LLM pre-training at scale
• Inference serving infrastructure: Low-latency, high-IOPS storage for model weight loading and KV-cache backing in multi-tenant AI inference servers handling thousands of concurrent requests
• GPU-Direct Storage pipelines: Direct PCIe Gen5 data path from SSD to GPU memory bypassing CPU, maximizing throughput in NVIDIA GPUDirect Storage-enabled deep learning frameworks
• Vector database and embedding stores: High-density NVMe storage for sub-millisecond approximate nearest neighbor (ANN) search indexes used in retrieval-augmented generation (RAG) architectures
• Hyperscale analytics and data lakehouse acceleration: Serving high-throughput columnar query engines (Apache Arrow, Parquet) with sequential bandwidth that keeps compute cores fully utilized
• Enterprise data consolidation and tiering: Replacing multiple lower-capacity Gen4 drives with single 15.36TB Gen5 units to reduce U.2 slot consumption, cabling complexity, and power draw per terabyte in dense 1U/2U rack servers
