Sorry? USB3.0 performance 'very good'?

Since noone outside LeMaker is able to test USB3.0 since t ...

Sorry for your reply, and i can't get any useful information to me.  As i said before, i need to consider the speed and cost, and i want to buy it now.  I hope you can recommend me the board which can exceed the Guitar in the storage. Finally you just give me a useless links, don't give me better board than the Guitar.

Well, the USB3.0 OTG cable is used to change the USB3.0 devicd mode to host mode.
We use the device mode to install a OS and use the host mode to connect a hard disk.
And it is ture that the write/read speed is influenced by the USB3.0 OTG cable but it is not the main factors.
The S500 can olny reach the speed leave, and, why you gays compare the performance between LeMaker Guitar and a computer???

I guess, you have to read the whole comment from TKaiser to understand what he meant. Quite long

  • In order to know how fast your hard disc can go, you have to check the hard disc first on a fast computer
  • Always use the same products (HDD, cable) to measure - so that your results are reproducible.
  • Always use the same procedure, but make sure it is a smart procedure.
  • Identify possible influences, like bad cable, customized cable, a cable from USB-to-SATA - remove these.

So you see, TK is aware that Guitar is not a PC.



@ cxy: Why do you want to replace Banana Pi Pro?

@ bprpcb : did you read TK's review on armbian.com and understand, that he can test by himself if the cable works?
