Accelerate Workflow with High–speed File Transfer
Leverage USB 3.0 technology
The Lexar Professional USB 3.0 Dual–Slot Reader leverages SuperSpeed USB 3.0 technology to deliver high-speed file transfer from card to computer, with a USB interface speed up to 500MB/s (reads up to 5 times faster than USB 2.0).1 This allows you to maximize the speed and bandwidth of USB 3.0 desktop and laptop computers, and supports CompactFlash (including UDMA 7), SD, SDHC, SDXC2, and SD UHS-I and UHS–II memory cards. This makes the reader an excellent choice for photo and video professionals looking to significantly improve workflow.
Quickly transfer files from both CF and SD card formats
While the high–speed Professional USB 3.0 Dual-Slot Reader supports the latest high–speed CF and SD formats, it's also backwards compatible with standard CF and SD cards, as well as USB 2.0. This provides you with convenient versatility on the go.
Save time with concurrent and card–to–card file transfers
The Lexar Professional USB 3.0 Dual–Slot Reader has the ability to read from both card slots simultaneously, and it also allows for easy file transfer from one card to another–further enhancing the reader's versatility.
Enjoy the convenience of innovative design features
The reader boasts an innovative, pop-up mechanism that protects the card slots by allowing you to close the reader when not in use. Also, its compact, portable design means you can take it on the go, and smooth contours help it slip easily in and out of your camera bag. The reader's sleek, glossy finish makes it a great addition to your workspace, and its LED activity light lets you know when your file transfer is complete. Includes a SuperSpeed USB 3.0 cable.
