Industrial-grade microSDHC 16 GB 25-pack

This pack contains twenty-five SanDisk Industrial microSDHC cards, each rated at 16 GB capacity with U1 speed class. They deliver sequential reads up to 80 MB/s and writes up to 50 MB/s. The series uses MLC NAND rated for up to 384 TB written, targeting embedded logging and data-intensive industrial deployments.

Installation notes and common issues

Cards insert into any standard microSD slot; no drivers or tools are required. Ensure the host device supports the 2.7 V to 3.6 V operating voltage range. The most frequent issue is selecting a consumer-grade card that lacks the extended temperature rating or the firmware features such as power-immunity, ECC and wear-levelling that prevent silent data loss in harsh environments.

Suited for embedded engineers, not consumer media

Engineers building dash-cams, telemetry loggers or outdoor sensors that must survive -40 °C to 85 °C will benefit from the health-status meter, programmable ID and host-lock features. Buyers who only need casual photo storage or a single card for a phone should consider standard consumer microSD lines instead.

Questions about this item

How can I verify the 80MB/s read and 50MB/s write speeds are performing correctly after installation?

Run a benchmark tool such as CrystalDiskMark or ATTO Disk Benchmark against the card and compare the sequential read and write results to the rated 80MB/s read and 50MB/s write figures.

What comes in the 25-pack and is any adapter or reader included?

The pack contains 25 SanDisk Industrial microSDHC 16GB U1 cards (model SDSDQAF3-016G-I); no SD adapter or USB reader is supplied, so purchase those separately if your device lacks a microSD slot.

Should I choose the 16GB U1 version or a different capacity for high-endurance logging?

This 16GB U1 model is rated for up to 384 terabytes written and operates from -40°C to 85°C, making it suited for intensive logging; select a higher capacity only if you need more storage per card.
