Product Information

Actual usable memory capacity may vary. 1GB equals 1 billion bytes. Lexar is not liable for any loss of data or images. The Lexar Dual-Slot Reader posted some very fast read and write speeds using both CompactFlash and Secure Digital cards. The fastest read speeds using CF cards were only slightly below those seen in the Lexar Professional Workflow CFR1, the fastest CF reader tested to date. The Dual Slot topped out at 156.8 MB/s using a Lexar 1066x 32GB CF card. SD card speed was excellent, for both reading and writing.

Compatibility is listed as Mac OS X 10.5+ and Windows 7/Vista/XP. The Lexar Professional Dual-Slot Reader is covered by a five-year limited warranty. Made in China. Maximizes speed and bandwidth of USB 3.0 computers, and supports the latest UDMA CompactFlash (including UDMA 7), SDXCTM, and SD UHS-I/UHS-II (SD 3.0) card formats Kingston’s MobileLite Plus SD reader supports UHS-II and UHS-I SD cards and delivers fast data transfer speeds thanks to its USB 3.2 technology. Do you need only a single port? Or do you want multiple ports for more than one card? This will also be a factor in your decision-making process. If you have multiple devices, consider getting a reader or hub that supports all devices.

What format of SD cards do you use? UHS-II is the second generation of SD cards released in 2013, which offers faster read/write speeds than the first generation. Most camera’s on the market use only UHS-I SD or MicroSD cards. But cameras with long buffer’s and fast continuous shooting speeds usually support these second-generation cards. Knowing which cards your camera uses, will help separate options, as some readers don’t support UHS-II cards. Alternatively, if they do, they only transfer at UHS-I speeds, defeating the whole purpose of buying them altogether. Read & Write Speed The dual-slot design is a significant advantage of this reader. It provides compatibility with SD and CF memory cards, including SDHC, SDXC, UHS-I, UHS-II, CF Type I, and CFast 2.0 cards. Having two slots allows you to transfer data between different card formats without the need for additional adapters or readers. This versatility is a time-saving feature, as it eliminates the hassle of switching devices when working with different memory card types.

As with the SD card format, there are several different types of CFexpress memory cards. CFexpress Type-B which is the most common for mainstream cameras. Opening up the reader is super simple – just push the two plastic pieces on the side and it comes right up. 3) Performance In the Dual Slot reader both cards can be accessed at the same time, although performance was slightly compromised when reading and/or writing two fast card simultaneously. In the best case the sum of concurrent transfers was just over 200MB/s. Copying from one card to the other measured about 90MB/s when using fast UHS-II SD and UDMA 7 CF cards. Being a USB 3.0 reader, as long as you have a USB 3.0 port on your computer, you should be able to push any kind of memory to its limits. I have tested out a few fast cards, like the SanDisk Extreme Pro series cards with this reader, and I was able to get very close to the advertised speeds. Write speeds varied from 120-150 MB on my SanDisk Extreme Pro 64 GB CF cards and reading speed was averaging between 140-150 MB/sec, which is what you can expect to see, provided that you have fast enough cards and internal storage to support such speeds. Keep in mind that most regular hard drives cap at slower speeds, so if you want to see anything over 100 MB/sec, you should probably copy from / to SSD or faster Flash drives. Here is a screenshot of the copy process at 150 MB/sec towards the end of the 2 GB file:

Close the reader when finished to keep the slots clean (This feature is especially useful when traveling).

As mentioned earlier, the Lexar Professional 3.0 Dual-Slot Reader is an amazing travel companion. I take it with me everywhere I go and it has not let me down once. What I like the most about the reader, is that the reader can be collapsed into its exterior plastic shell, not only making the card reader more compact, but also hiding those slots from dust and other potential debris. While I try to keep my bag clean, I have been to remote areas with a lot of dust, sand, rain / snow – hazards that can permanently damage any piece of electronics. So it is nice that the memory card readers can be hidden away when not being used. Don’t expect the reader to be waterproof though. If the reader falls into water or gets subjected to a lot of moisture, shake the water out and let it sit for a few days in dry environment and it should be good to go. There is no active power of any kind or batteries, so unless you plug it in, you won’t kill the unit.

I use an iMac running macOS Sierra and if I insert a 64 GB card into a USB 2 reader I have always got message that the OS cannot repair the card. I always ignored this and never had a problem. However, with the USB3 reader, I do not get this message. The Lexar Dual-Slot Reader was tested with a variery of CompactFlash and Secure Digital cards.
