Built with four 10 Gb/s USB 3.1 Gen 2 Type-A ports, the RocketU 1344A 4-Port USB 3.2 Gen 2 PCIe 3.0 x4 HBA Controller Card from HighPoint allows users to connect four USB 3.2 Gen 2, USB 3.2 Gen 1, USB 2.0, and USB 1.0 devices to their compatible Windows 8 and later, macOS 10.9 and later, or Linux system using a PCIe 3.0 x4, x8, or x16 slot. This card has a full-height form factor and can be used to connect to external drives, docks, drive enclosures, printers, scanners, mice, trackballs, flash drives, card readers, and more.

Please note that while each individual USB port supports up to 10 Gb/s of bandwidth, there are two USB chipsets, each of which drives two of the four USB ports. Each USB chipset provides two of the ports with 10 Gb/s total, so if both USB ports from the same chipset are in use, each port will only run at 5 Gb/s. All in all, this card has 20 Gb/s of total bandwidth available.
