What customers say
This interface card earns praise for successfully adding fast 10Gbps USB 3.1 Gen 2 connectivity to older desktops, extending their usability. Users appreciate the robust build quality and the simple installation on modern Windows systems, often achieving a true plug and play setup. The card delivers reliable, high data transfer speeds when fully operational. However, a significant caveat involves power. Instability and dropouts frequently occur if the required auxiliary SATA power connection is overlooked or insufficient. While Windows compatibility is strong, some users encounter driver difficulties with specific Linux setups or older motherboards. The overall value hinges on the buyer's readiness to ensure proper power delivery to unlock the card's full performance potential.
