- pdonis 9y agoI see. Does anyone know what the rationale for that design decision was? I'm comparing to, for example, the Dragino, which is in the same general price range but does not have this, um, "feature".
- voltagex_ 9y agoPossibly because there was nowhere else to hang the port off with that Broadcom SoC. See also the myriad SoCs and devices that use a USB->SATA converter where I really just want SATA (e.g. a little known, obscure device called the Playstation 3).
