I buy this hard drive to permanently connect the TV to a surprise and it is not recognized! I tried on other TVs, same result. So I use it to store my data since the former was almost full. But again I have problems because some days, there are bad contact to the USB cable on the case of the level and the computer does not see the drive. Simply disconnect and reconnect it to come back in order. The flow level, I did not measure with software but it does not seem to me terrible.
