Package:

one pcs usb with a black box

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!

16GB = approximately 14.9GB-15.2GB

32GB = approximately 28.5GB-29.5GB

64GB = approximately 58.0GB-60.0GB

128GB = approximately 109.0GB-117.0GB
