Lexar Professional Workflow HR2 Review

The Lexar Professional Workflow HR2 is a four-bay reader and storage drive hub that uses both Thunderbolt 2 and USB 3.0 connectivity, allowing for compatibility with both Windows and Mac OS platforms. We previously review its predecessor, Professional Workflow Reader, and were very impressed with its multi-card performance speeds and sturdy build. With the new Lexar hub, users can pick and choose from a variety of combinations of readers and storage drives to suit specific use cases and specialized workflows. The biggest advantage of Lexar’s Professional Workflow line is that users will be able to save time due to its ability to transfer and back up data from multiple cards at once, which allows professionals to quickly edit and share their files. Not only does the Professional Workflow HR2 offer quite a bit of flexibility, Lexar indicates that the hub provides the performance needed for high-speed transfer and backup of RAW images, high-res photos, and HD, 3D, and 4K video. In addition, the HR2 is also backwards compatible with Thunderbolt and USB 2.0 using the same cables and connectors.

The Professional Workflow HR2 gives users the choice of six readers and two storage drives with the readers supporting SDHC/SDXC UHS-I and UHS-II, CompactFlash UDMA 7, XQD, CFast 2.0 (USB 3.0 or Thunderbolt), and microSDHC /microSDXC UHS-I formats. The storage drives are offered in 256GB and 512GB capacities and are quoted to deliver read transfer speeds up to 450MB/s and write speeds up to 245MB/s using USB 3.0 connectivity (with faster performance using Thunderbolt 2). In addition, Lexar has conveniently packaged their readers and storage drives with USB cables so workers can use them on their own as a mobile storage solution. Because the Professional Workflow HR2 has modular design, it has the ability to adapt to changing technology standards. When Lexar, or other companies, release new card formats and additional storage drives for the HR2 hub, users can easily swap in the newer technology making it a “future-proof” card reader.

The Professional Workflow HR2 is priced at roughly $200 and also comes in an H1 USB 3.0-only model, which goes for only $56. Both devices are backed by a 2-year warranty.

Design and build

The Lexar Professional Workflow HR2 looks very similar to its predecessor, with its rugged build and slick looking design. It is comprised of a shiny, black chassis and is branded with the Lexar logo at the bottom, while the 4 bays are accessible via the front panel in between the ventilation grills.

The card readers and storage drives come with a silicone cover, which can be used to protect it from dust and other elements; this is pretty useful for workers who travel with their readers or frequently store them in and out of a bag. The drives are also equipped with an LED capacity meter, so users can quickly see the available storage space.

The back panel is home to the power connector and USB 3.0 and Thunderbolt 2 connectors. For users looking to daisy-chain the hub, simply connect one Thunderbolt 2 cable from the HR2 to your computer or other device and then connect the hub to the Thunderbolt 2 cable from the next device (e.g. a monitor or hard drive). The Lexar Professional Workflow HR2 allows up to six devices for daisy-chaining using one port on your computer. In addition, Lexar says to place the hub at the beginning of the chain, closest to your computer, in order to ensure the best possible performance.


To test the performance of the Lexar Professional Workflow HR2, we used a current gen MacBook Pro with a Thunderbolt 2 connection using the Blackmagic Disk Speed Test tool. For our testing we used a SanDisk Extreme PRO 64GB CompactFlash Memory Card and a SanDisk Extreme PRO SDHC/SDXC UHS-II 16GB Memory Card. Each card was tested separately using a 5GB files size.

Our compact flash configuration posted 98.3MB/s read and 78.8MB/s write during a 5GB file transfer. Using our SD card setup, we measured read and write speeds of 251MB/s and 104.1MB/s, respectively.


The Professional Workflow Reader HR2 reader and storage drive hub is targeted mainly towards multi-media enthusiasts, offering a ton of flexibility for those who use a variety of different memory cards throughout their workflow, staying true to its name. With the release of the HR2 (and HR1), Lexar certainly has an even stronger grip on this specialized market, as their readers offer unique functionality when compared to its competition. While there are an abundance of multi-card readers available, none of them have the modular design that the Professional Workflow has, giving Lexar’s reader a huge edge in the market since it can adapt when newer technology is released. This flexibility makes the HR2 significantly more valuable as well, eliminating the need to buy an entire new device as technology changes. As such, the Professional Workflow HR2 reader and storage drive hub is available at a street price of roughly $200 (not including the card readers) while the R1 model is available at only $56 dollars for who simply need a USB 3.0 connection.

As far as its performance goes, the Professional Workflow HR2 offered results that were below what was quoted by Lexar. When using our compact flash configuration, we measured the hub with 98.3MB/s read and 78.8MB/s write during a 5GB file transfer, while our SD card setup recorded read and write speeds of 251MB/s and 104.1MB/s, respectively. Performance is going to be based on the specific media used. The limitation would be in a specific media card, not necessarily the dock itself. Looking at the testing from our reviews of the SD card and compact flash, the speed for the SD card is better through the dock and the compact flash is about the same. However, the speeds we saw are more than sufficient for most editing professionals. 


  • Adapts to new technology with modular design
  • Supports both Thunderbolt and USB 3.0
  • Individual card readers can come out for mobile workflows


  • Can be a bit expensive after purchasing the four readers/storage drives

Bottom Line

Though a bit pricey, the Professional Workflow Reader HR2 is an excellent reader and storage drive hub, offering users the peace-of-mind that their purchased device will be able to adapt new technology.
