Technical Guides and Comparisons
These guides answer the comparison questions buyers ask before specifying a part: whether TF and MicroSD are the same thing, which physical format fits a product, what cell type and speed class actually mean, where the consumer/industrial line falls, and what a NAND grade does and does not tell you. Each one is written to be usable on any supplier’s product, not only ours — a comparison that only describes our own range is marketing, not a guide.
TF Card vs MicroSD
The same physical format, two names, and one reason both are still used.
UDP vs COB vs PCB
Three physical formats, three different places in your product.
SLC vs MLC vs TLC
Bits per cell, endurance, cost — and why the label alone is not enough.
U1 vs U3 vs V30
Four markings, four different things measured, one that matters for you.
A1 vs A2
Random IOPS, not video speed — and only relevant if you run apps from the card.
Consumer vs Industrial Flash Storage
Temperature range, endurance, supply life — and what each costs.
NAND Flash Grades and Sourcing
Grade, source, and the difference between the two questions.
