Samsung SSDs hit 14.5GB/s to bridge local AI memory wall

Samsung's new PM9E1 PCIe 5.0 SSD achieves sequential read speeds of 14.5 GB/s, matching the bandwidth of single-channel DDR4 memory. This hardware milestone is specifically optimized for "AI PCs," allowing massive local LLMs to be loaded into memory in under a second and enabling viable inference even when models exceed available VRAM.

// ANALYSIS

The "memory wall" is finally crumbling as storage bandwidth catches up to legacy RAM, making 70B+ local models practical for the first time.

–14.5 GB/s transfer rates effectively treat the SSD as a secondary tier of slow RAM, supporting inference offloading at 2-4 tokens/second.
–Integrated Presto controllers are built on 5nm processes to handle the high-throughput, low-latency demands of local AI workloads.
–50% improvement in power efficiency makes these drives ideal for mobile AI workstations and "Copilot+" laptops.
–This hardware shift will likely reduce the industry's reliance on aggressive quantization and cloud-based inference for consumer devices.
