Next evolution of USB 3.0 and eSATA interface card

The FASTA-6GU3 Pro is the next evolution of CalDigit's popular USB 3.0 and eSATA interface card. This PCIe card has been revamped with the latest USB 3.0 Protocol and SATA 6G chipsets to deliver increased performance. The FASTA-6GU3 Pro's USB 3.0 ports now support UASP (USB Attached SCSI Protocol), which dramatically improves the performance and efficiency of the USB 3.0 interface.

When paired with a UASP compatible device, such as the CalDigit AV Pro SSD, the FASTA-6GU3 Pro can deliver dramatically increased performance compared to other USB 3.0 PCIe cards using the traditional, less efficient BOT Protocol (Bulk Only Transfer). UASP improves upon BOT by allowing multiple command queuing, and the execution of out of order commands. It also improves the efficiency of USB 3.0 by freeing up system resources for more important tasks. Featuring two USB 3.0 ports and two eSATA ports, the FASTA-6GU3 Pro gives users the flexibility of dual interfaces while saving a precious PCIe slot. The FASTA-6GU3 Pro also has two internal SATA ports that allow users to connect up to two additional hard drives inside their workstation.

The FASTA-6GU3 Pro features the latest USB 3.0 technology called UASP (USB Attached SCSI Protocol). This allows the FASTA-6GU3 Pro to use all the available bandwidth of the USB 3.0 interface in order to get the fastest possible speeds through its USB 3.0 interface. The majority of USB 3.0 PCIe cards on the market do not offer this latest USB 3.0 Protocol. The FASTA-6GU3 allows you to get the best possible performance from your connected devices.


The two eSATA ports on the FASTA-6GU3 Pro feature the fastest 6G eSATA speeds that allow users to get the maximum performance possible from their eSATA devices. The FASTA-6GU3 Pro is also fully compatible with legacy eSATA devices.

Internal SATA

The FASTA-6GU3 Pro features internal SATA ports that allow users to connect two extra HDDs inside their workstation.

Hot-Pluggable eSATA Interface

The FASTA-6GU3 Pro's eSATA interfaces are hot-pluggable. This means that users do not need to turn off their computer when connecting devices.
