Lexar LRW307URBNA Overview

  • 1Description

The Lexar Professional USB 3.0 Dual-Slot Reader (UDMA 7) is a memory card reader equipped with a USB 3.0 interface supporting data transfer rates of up to 500MB/s. That's up to five times faster than USB 2.0 speeds. Achieve a maximum read speed of 150MB/s with the fastest compatible memory cards: CF 1000x. The reader is also backwards compatible with USB 2.0 devices. It supports UDMA (Ultra Direct Memory Access) 7 cards, which feature substantially accelerated speeds. Compatible card formats include CompactFlash (CF), SDXC / SDHC UHS-I, and SD.

The Lexar Pro USB 3.0 reader is a superb choice for photo and video professionals seeking to significantly speed up workflow and get the most out of their sophisticated memory cards and computers. However, the card will also serve amateurs and enthusiasts well. The reader allows for concurrent transfers--in other words, it's capable of reading both SD and CF cards simultaneously. Additionally, it enables easy card-to-card file transfers. The LED activity light indicates when a transfer is complete.

The reader's convenient pop-up design protects card slots when they're not in use. Its compact size makes it easily portable, as do its smooth contours, which allow you to slip the device easily in and out of your photo bag or briefcase.

Like all Lexar memory equipment, the reader has been subjected to extensive testing in the Lexar Quality Labs to ensure the highest performance, compatibility, quality and reliability.

Note: Speed may vary based on system configuration and card used. SDXC format not supported on all OS platforms.

    Lexar LRW307URBNA Reviews

    Professional USB 3.0 Dual-Slot Reader (UDMA 7) is rated 4.7 out of 5 by 815.
    Rated 5 out of 5 by from Well designed, compact and quick I've been using an LRW025URBNA reader by Lexar. What I did not realize until damaging a UDMA 7 compact flash card is that this reader is not UDMA 7 compatible. After extensive chats with Lexar technical services I decided to replace it with this reader by Lexar. As I learned, the hard way, when you use a Non UDMA 7 reader with a UDMA 7 card it can work; however the reader is too slow for the card. The card acting too fast actually forces corruption into the card. Over time whether it be one use or hundreds of uses the card will eventually find the corruption and cause it to have major problems or fail altogether. Hope this helps.

    Rated 1 out of 5 by from Will not work with New Mac The other reviews are correct. It will not work with any new Mac with usb 3.0 ports. I too have spent hours talking with lexar support. They pretend that you are doing something wrong. They eventually sent me a replacement with the new firmware, same issues. You can get it temporarily working but you have to shut down the computer zap the pram, but once you insert another card the reader will not recognize it. I wish I could send it back.

    Rated 2 out of 5 by from Not compatible with new Sony SDHC UHS-1 I purchased this item December 2012 and it has worked perfectly with all of my SDHC cards: Transcend Class 10 and Sandisk Extreme Pro UHS-1. However, I recently purchased the new Sony 94mb/s UHS-1 16gb card and when I put the Sony card in this reader it causes my newly built system to lock up. When the system tries to read the card it causes the reader to unmount and re-mount (disconnects then says 'found new hardware'). Put my other cards back in, reads fine. Put new Sony card in, locks up again. Put new Sony card in 2 year old Sony card reader (MRW-EA7) and works fine! Very sad that in today's modern times there are still card/reader compatibility issues.

    Rated 5 out of 5 by from Firmware upgrade for this device Purchasers may not be aware of the upgrade referred to below. Lexar releases firmware fix for USB 3.0 reader incompatibility Tuesday, July 10, 2012 Lexar today has posted a firmware update for its Professional USB 3.0 Dual-Slot Reader that corrects an incompatibility with the USB 3.0 ports of Apple's newest notebooks, including the MacBook Pro with Retina Display. Firmware v.1.0.0, bundled with a utility for installing it, is available on the Lexar downloads page.

    Rated 3 out of 5 by from Doesn't work well with Sandisk 32G CF I purchased this card reader recently and found that it doesn't work well with Sandisk extreme pro 32G 90MB/s UDMA7 CF card. It has the latest firmware however it averages only 45MB/s read on a USB 3.0 port while my other cheap card reader can do 90MB/s on the same card same file and same USB3.0 port. The SD card slot works as expected. At first i thought it's because i got a defected product and after exchanging for another one the issue remains. I tried to change the cable, port and results are the same. Called tech support and they are not aware of any compatibility issue but also don't know what could be the cause.

    Rated 5 out of 5 by from A flawless standard card reader If you want the best all-round card reader for dealing with UHS-I SD and UDMA-7 CF cards, here it is. With USB 3, it close to maxes out the stated speeds of the top cards -- Sandisk's Extreme Pro 95MB/sec SDHC and Lexar's 1066x (160MB/sec) UDMA-7 CF -- for transferring into the computer. And it does so reliably and without hesitation or brand discrimination. The only limitation would be if you own one of the handful of cameras with UHS-II support, as this version of the Lexar reader does not have the extra row of contacts for increasing import speeds. If you purchase another product and you intend to use the CF slot, make sure it supports UDMA7; some of them still only support UDMA6.

    Rated 5 out of 5 by from This is a great product. After reading an article about CF card readers in which this was the recommend card reader, I went to the Lexar website to get more information about this product and decided to order one. This reader is USB 3.0 capable but is backwards compatible with USB 2.0. So this reader worked perfectly with the USB 2.0 port in my computer. Not only that but one can insert both a CF card and an SD card at the same time and they will appear as different drives and both be accessible. I needed no additional software on my computer to run the card reader, I just plugged it in and it worked. I highly recommend this card reader.

    Rated 5 out of 5 by from Great Time Saver!! Was using a USB 2.0 multi-card reader (not a Lexar) that was okay for photo downloads but really failed when it came to video transfer. Recording HD video onto SanDisc Ultra SDHC cards (30MB/s) and downloading onto iMac OS 10.6 USB 2.0. Previous card download speeds for video were extremely slow (5-1/2 hrs for 12 GB of HD video). Just downloaded 18 GB of same quality video. Time to download? 11 minutes. And that included swapping from one card to another. In case you're wondering, I did not upgrade either my cards or my computer; just a very wise investment of a few dollars. If your time is important(and whose isn't), get this card reader.
