Western Digital CL SN520 NVMe SSD

High-Performance Industrial Storage

The Western Digital CL SN520 NVMe SSD (SDAPNUW-128G-1022) is a 128GB M.2 2280 PCIe Gen3 x2 SSD built on 64-layer 3D TLC NAND. Designed for industrial and commercial applications, it delivers sequential read/write speeds up to 1,700MB/s and 1,300MB/s, with 220K/175K random read/write IOPS (4K). Ideal for IoT, edge gateways, and surveillance, it ensures high performance in compact systems with low power consumption.

Durability and Wide Temperature Range

With a 200TBW endurance rating and a 1.75M-hour MTBF, the CL SN520 is built for 24/7 reliability in demanding environments. Its wide operating temperature range (0°C to 85°C) reduces cooling needs for applications like in-flight entertainment and factory automation. The single-sided M.2 2280 form factor ensures compatibility with space-constrained devices, though some users report used drives in OEM packaging, which may affect initial trust.

Cost-Effective and Scalable Design

The CL SN520’s PCIe Gen3 x2 interface and NVMe 1.3 architecture offer a cost-effective solution for high-performance needs, with a 3-year warranty for extended longevity. It supports applications requiring large data writes, such as surveillance and edge computing. While optimized for industrial use, it’s also compatible with PCs and laptops, though some users note the lack of DRAM cache may impact heavy workloads.
