    REVIEW: Sonnet SF3 CFexpress/QXD Pro Thunderbolt 3 Card Reader – All That Speed!

    The Sonnet SF3 Series CFexpress/XQD Pro Card Reader is one of the few on the market today that will allow you to use your CFexpress card to its full performance capabilities.  Its build is beyond reproach with a smooth brushed aluminum exterior with ribbing that acts as a heatsink, two ports in the front that will accommodate CFexpress Type B or XQD cards, as well as two Type-C [Thunderbolt 3] ports at the back to allow for daisy chaining as Thunderbolt 3 does.
