Overview
Silicon Power's industrial division builds storage around a single constraint: operation where commercial parts are out of spec. The MEC3H0S is the flagship, a PCIe Gen 4 NVMe M.2 2280 drive that holds -40 C to 85 C across a capacity range extending to 7.68 TB, with sequential performance up to 7,200 MB/s read and 6,800 MB/s write. A 12-layer PCB and a no-moving-parts design give it the mechanical stability that warehouse, outdoor and vehicle deployments require.
The portfolio extends in both directions. The Cinema Series addresses high-end recording workloads where sustained write bandwidth and wide-temperature tolerance matter at the same time, while the industrial DRAM modules push the upper bound to 105 C for telecom and logistics equipment that runs hot. For less demanding designs, commercial-temperature SATA models such as the M.2 2280 A55 cover 0 C to 70 C with a 1,500,000-hour MTBF.
Practically, the family is aimed at designers who need one qualified storage part that survives a temperature excursion without a retry: outdoor kiosks, warehouse automation, transport and fleet systems, and industrial PCs installed in unheated cabinets.
Key Benefits
-40 C to 85 C on PCIe 4.0 NVMe — full performance across the industrial range. Up to 7.68 TB in M.2 2280 for local data retention at the edge. 12-layer PCB, no moving parts for vibration and thermal-cycling stability. Wide-temperature DRAM to 105 C completes the memory picture.
Applications
Outdoor and warehouse embedded systems, transport, fleet telematics and rail, industrial PCs in uncontrolled environments, video and high-end recording platforms, and telecom or logistics equipment exposed to elevated temperatures.
