- | The solution | + | Typically a 2.5" drive requires about **1 A** at startup and about **500 mA** at read/write average. It is likely that the X96 Mini's circuitry provides USB ports with barely the minimum required by the USB 2.0 standard, which is **5 V, 500 mA**, regardless the rating of the power supply (mine was rated 4A). |

I measured the disk performance on both the two USB ports (the white one and the black one), they measured exactly the same transfer rate. For the test I used the **hdparm** tool: | I measured the disk performance on both the two USB ports (the white one and the black one), they measured exactly the same transfer rate.
