Edge AI cameras, dashcams and industrial gateways write continuously. How to choose between A1, A2 V30, high endurance, surveillance, pSLC and SD Express grades.
The microSD market has changed shape. With fewer phones offering a card slot, 2026 industry analysis describes demand shifting from phone expansion toward 8K video capture, drones, vehicle DVRs, AI surveillance cameras and industrial handhelds. Those workloads write continuously, often around the clock, and depend on sustained write behaviour, power-loss integrity and temperature range far more than on peak read speed. Analysts describe a market splitting into a commoditising consumer tier, a professional UHS-II/III imaging tier, and an industrial / edge-AI tier where high TBW and -40°C to +85°C operation drive growth.
That is why capacity is a poor buying criterion. A 128 GB A1 card and a 128 GB industrial pSLC card can carry the same capacity marking and behave completely differently after eighteen months of continuous recording. For dashcams, surveillance and fleet recorders, specify endurance (TBW), wide-temperature operation and power-failure protection, and get the endurance figure in writing. For phones, tablets and general retail, A1 or A2 V30 is the economical choice. SD Express only pays off in a host that actually supports the PCIe interface.
NandCell publishes seven microSD / TF grades: A1 everyday, A2 V30, Pro, High Endurance, MAX Endurance for surveillance, industrial pSLC, and microSD Express. Each has its own static specification page, and the quality page documents the grade comparison and test conditions. Sample specifications are indicative and are confirmed against the datasheet for the ordered model. Tell us the host device, the write duty cycle and the operating temperature and we will recommend the grade that fits — including when a cheaper grade is sufficient.
