The problem is not to compare speed with windows and speed with ubuntu. but why with ubuntu, it is necessary to buy an extended USB2 cable to access the partitions... Because without this add-in, it is impossible to read the contents.
Note: windows read the contents without this add-in'. Note: DMESG ERROR => partitions are not mounted!!!
