We analyzed the cause of the problem that the USB transfer speed of iAUDIO 7 was different from the specifications. We found out that some of the iAUDIO 7 16 GB products were set the landmemory cluster as 8 KB. It should be 16KB.
If the iAUDIO 7 16 GB product is set 16 KB memory cluster, the transfer speed (Write: max 40Mbps, Read: max 40Mbps) will work well. (Please remind that the transfer speed will be dropped if you set other unit.)
Please check the below how to set the memory cluster unit as 16 KB of iAUDIO 7 16GB.
We regret the inconvenience caused and kindly request your understanding. We strive more to provide the best customer service as musch as possible.
Thank You
