Attention:
Every USB are real capacity,not update capacity,so each one can be test via H2 software.
Capacity detail :
Flash memory producers are using decimal arithmetic:
1KB=1000Bit, 1MB = 1000KB, 1G = 1000MB
And different factories will produce different capacity USB flash drives. So it is normal to has little capacity deviation!
32GB = approximately 28.0GB-29.5GB
