File transfer speed is slow

When transferring footage from an SD card to external SSD I’m getting at most 25 MB/s. The SD card is a Lexar 2000x with 300MB/s and V90 and the SSD is an MD 4tb My Passport. I’m using an Acer 7 in 1 usb hub which claims up to 5GB/s transfer speeds. I don’t know what else to do to increase speeds but when it took multiple hours to transfer an hour and a half of 4k footage it was quite irritating! Any advice would be greatly appreciated.
