Vendors are using Flash memory decimal arithmetic: 1 MB = 1000KB, 1G = 1000 MB
Calculated, operating system with binary arithmetic: 1 MB = 1024KB, 1 GB = 1024 MB;
So there are some differences between display capacity and nominal capacity of flash memory products.
For sample ,Card 32GB, showing 29.90GB as 2.1GB is reserved for bad sectors, and it's not about the systems we use but it's about reserved space. Every drive has some space reserved for bad sectors! Thats why it's 29.9GB and not 32GB, thanks for your kindly understanding!
