💾 Samsung 9100 Pro NVMe SSD PCIe 5.0 (NVMe 2.0) Up to 14.8 GB/s
The Samsung 9100 Pro is Samsung’s first true PCIe 5.0 / NVMe 2.0 consumer SSD, delivering sequential reads up to 14.8 GB/s and writes up to 13.4 GB/s. Powered by the custom Presto controller and 236-layer V8 V-NAND TLC, it’s a serious upgrade for AI/LLM workloads, data science, and workstation creatives.
⚡ Real-World Performance
Independent reviews place the 9100 Pro at the top of Gen5 drives. Tom’s Hardware highlights the 8 TB model with endurance up to 4,800 TBW. In mixed real world tests, reads commonly land around ~12.4 GB/s still more than 2× the fastest PCIe 4.0 SSDs.
🔍 Why It Matters for AI & LLMs
- GPU offloading / oversubscription: When VRAM is exhausted, model weights and KV caches spill to disk; Gen5 bandwidth reduces stalls and keeps tensor cores busier.
- High throughput dataset streaming: Ingest multi GB shards (images, parquet, text) at Gen5 speeds to minimize input bottlenecks.
- Fast checkpointing: Save and resume multi-gigabyte training states quickly to shrink downtime between runs.
- Concurrent I/O: Sustains parallel reads/writes while the GPU computes useful for data loaders and multi process training.
“When I moved it to a PCIe slot not shared with the GPU, speeds rose by 10–20%.” — Community report (slot/lanes layout can impact Gen5 throughput)

🏗 Scalability, Compatibility & Limits
To reach peak numbers you need a motherboard with true PCIe 5.0 x4 wired lanes, adequate cooling (heatsink + airflow), and a slot not sharing bandwidth with a GPU. Consoles like PS5 and many mid-range desktops won’t fully leverage Gen5 bandwidth yet. Thermal limits or shared lanes can pull sustained speeds closer to ~12 GB/s still class-leading.
