TUSB9260 Performance

Other Parts Discussed in Thread: TUSB9260, TUSB7340

We included the TUSB9260 in our system. It is connected to a very fast SATA SSD (Read/Write up to 500 MByte/s).

But when connecting it to a PC using the TUSB9260 we only get download speeds of about 40 to 60 MByte/s.

We tried different PCs and both Windows 7 64bit  and Linux. The chip is correctly detected as a USB 3.0 device (xhci controller).

We hoped the transfer would be much faster.

    Hello,

    The throughput is highly dependent on the host controller and the HDD, we have easily got  251MB read and 152 MB write using the TUSB7340 host controller using UAS support and U1/U2 disabled.

    What are the characteristics of your system?

    Regards.
