Lexar Professional Multi-Card 25-in-1 USB 3.0 (500MB/s) Memory Card Reader - White

Product Information

Actual usable memory capacity may vary. 1GB equals 1 billion bytes. Lexar is not liable for any loss of data or images. 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. Compare prices on the Lexar Professional Dual Slot Reader reader. The lowest prices are highlighted in the table below. Card Reader Close the reader when finished to keep the slots clean (This feature is especially useful when traveling). 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.

The Lexar Dual-Slot Reader was tested with a variery of CompactFlash and Secure Digital cards. The Lexar Professional 2000x UHS-II 64GB SDXC measured 268MB/s sequential read speed and 250MB/s write speed. Using UDMA7 CompactFlash cards such as the Lexar Professional 1066x 128GB, the reader reached over 158MB/s read and 155MB/s write speeds. Results using various cards can be viewed in the table below. With UHS-II SD cards the Dual Slot LRW400U was not quite as fast as the Lexar SR2 UHS-II SD card reader. The CF card write speed improved over the previous Dual Slot reader, up from 139MB/s to over 155MB/s with the new reader. Maximizes speed and bandwidth of USB 3.0 computers and the latest UDMA CompactFlash® (including UDMA 7), SDXCTM, and SD UHS-I (SD 3.0) card formats Bright blue LED turns on when a card is inserted and flashes when a card is being accessed. The CF card slot offers a firm and positive feel, with little play. The CF card inserts to about 3/4-inch (19mm) depth which should eliminate any concern of bent pins. The SD card slot is about 5/8-inch (16mm) deep and has a similar precise feel. Both cards protrude the same amount and with only 3/32-inch (2.5mm) between them grasping the smaller SD card can be difficult when a CF card is inserted. 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.

Introduction You might want to add that the provided cable is micro USB (3.0); the same some Nikon cameras use and different from the other Lexar readers you reviewed, who use full-size USB 3.0 Just a short Lexar Professional USB 3.0 Dual-Slot Reader review to mostly say "This is what I'm using".

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: Updating USB 3.0 Dual-Slot Reader driver benefits include better hardware performance, enabling more hardware features, and increased general interoperability.

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.
