How to read a technology specification
- Separate the product type, form factor and interface—they may describe different things.
- Check whether a number is an interface limit, a tested device result or a marketing claim.
- Confirm units and conditions before comparing two values.
- Use the exact device model and official documentation for compatibility decisions.
