SanDisk SN670 — Enterprise PCIe Gen5 QLC NVMe SSD

Specifications

Overview

The SanDisk SN670 is a next-generation enterprise NVMe SSD built on the UltraQLC platform, leveraging BiCS8 218-layer 3D QLC NAND with 2Tb die density. Delivering PCIe Gen5 throughput at capacities up to 122.88TB in a standard U.2 form factor, the SN670 targets AI data pipelines, capacity-intensive analytics, and hyperscale storage infrastructure. Direct Write QLC eliminates the SLC cache bottleneck, providing power-loss-safe writes on the first pass with up to 68% faster random read and 55% faster random write vs. competing Gen5 QLC drives.

Key Benefits

Massive Capacity: Up to 122.88TB per drive — 2× the capacity of Gen4 QLC alternatives. Gen5 Performance: PCIe Gen5 x4 interface with NVMe 2.0 compliance delivers double the bandwidth of Gen4 at equivalent power. UltraQLC Architecture: Direct Write QLC with Dynamic Frequency Scaling eliminates SLC cache dependency, optimizing sustained write performance and endurance at scale. AI-Ready: Purpose-built for AI data ingest, preparation, and data lake workloads — the highest-capacity enterprise SSD in the SanDisk portfolio.
