128 GB USB 3.0 flash drive

The Transcend JetFlash 790 provides 128 GB of portable storage in a capless design. A slide-out USB Type A connector protects the interface when not in use. An LED indicator shows read and write activity at a glance. The lightweight 4.9 g body includes a loop for a lanyard or key ring.

USB 3.0 speed limited by host port

SuperSpeed USB 3.0 transfers are supported, but actual throughput depends on the host controller and cable quality. The drive falls back to Hi-Speed USB 2.0 on older ports, reducing maximum transfer rates. No external power is required for operation.

Slide-out connector eases installation

Insert the drive by sliding the connector forward until it clicks into the port. The capless mechanism removes the risk of losing a separate cap. Ensure the slider is fully extended before removal to avoid damaging the connector or port.

Questions about this item

Should I choose the 128 GB version or is a larger size available?

Only the 128 GB capacity is offered for the JetFlash 790 series.

What read speed will I actually see when the drive is plugged into a USB 3.0 port?

The drive supports SuperSpeed USB 3.0, so transfer rates are limited by the 5 Gbit/s bus and the flash memory inside.

Does the USB 3.0 Type-A connector limit performance on newer USB-C laptops?

The Type-A plug works with USB 3.0 and falls back to USB 2.0; an adapter is needed for USB-C ports but does not increase the 5 Gbit/s ceiling.
