SanDisk Ultra Dual USB Drive review: Android file transfers made easy

SanDisk Ultra Dual USB Drive (32GB) $30.00 SanDisk’s Ultra Dual USB Drive is a bit pricey, but it’s a super convenient means of transferring files between Android smartphones and tablets and your computer.

There are lots of ways to transfer files between your PC and an Android device, but the simplest method has been to tether one to your PC using a cable. SanDisk has a better idea: Its Ultra Dual USB Drive can be used with Android smartphones and tablets and with PCs. 

The thumb drive has a standard Type A USB 2.0 plug on one side, and a Micro-B USB 2.0 plug on the other. I tested the 32GB model with an HTC One smartphone. Both of the drive's connectors are protected by a sliding plastic shell that automatically retracts when you push the plug into a USB port (you’ll need to pull the covers back out when you unplug it). Due to the thickness of the thumb drive’s shroud, I had to pop the bottom of my phone out of its Speck case. But I’ve encountered the same issue with right-angled headphone plugs, so this isn’t a showstopper by any means.

The thick plastic cowl on the Dual USB Drive might force you to remove your smartphone or tablet from its case before you can plug it in. 

Having both connectors makes it extremely easy to transfer files between your Android smartphone or tablet and your PC. Move or copy files from your phone to the storage device, unplug it, plug it into your PC, and move or copy those files to that device (and vice versa). If you use a cloud-storage service, you can copy files there as well. The storage device measures just 1.5 inches long and 0.75 inches wide. It has a lanyard ring so you can add a tether, but the hole is extremely small.

SanDisk’s Ultra Dual USB Drive would be a lot faster if it was outfitted with a USB 3.0 interface.

The HTC One doesn’t have its own file-manager software, although there are a number of free Android apps available in the Google Play store. I’ve been using ES File Manager for a while, but I’ve since switched to SanDisk’s free Memory Zone, which has a much more polished user interface. Rather than having to drill down into the phone’s directory structure, Memory Zone indexes and sorts all the files it finds on the phone and on any storage device that’s plugged into it. You can add any cloud-storage services you use—such as Dropbox—and the app will index all the files stored there as well.

Once the files have been indexed, you can press the music icon to see a list of all the music files in storage. Press the landscape icon and you get a list of all the photos. There are also icons for movies, documents, and apps. Tap the file, and a Complete Action Using pop-up menu appears. If it’s a music or video file, you can play it with whatever media player apps are installed on the device. If it’s a photo, you can view it using your favorite photo editor, and so on.

SanDisk's free Memory Zone app is a very handy Android file manager—and it's free.

Press and hold a file name, and a pop-up menu will appear giving you the option to copy the file to another storage device or to your cloud account. You can also rename or delete the file, make the file private (these are password protected), or share the file on Facebook. Memory Zone also has a backup/restore function that you can set to automatically back up all or selected files from your phone to a USB storage device or—more practically—to your cloud-storage service.

This element of the app informs you of the backup’s progress, how fast files are being transferred, and an estimated time of completion. Backups can be performed over a 4G connection or limited to using Wi-Fi, so they don’t suck up your cellular data quota.

SanDisk’s Ultra Dual USB Drive would be a lot faster if it were outfitted with a USB 3.0 interface, but that would also make it more expensive. It’s already a bit pricey, with the 32GB model selling for $30. That’s a $10 premium over a conventional 32GB USB thumb drive, and you can buy a 10-foot micro USB cable for as little as a buck and a half. (SanDisk also offers 16GB Dual USB drives for $20, and 64GB drives for $50). But a cable isn’t nearly as convenient.

SanDisk isn’t the first company to hit on the idea of a two-headed storage device. Sony announced its own line of two-in-one drives last December. But Sony’s models top out at 32GB, and the company doesn’t offer an Android file manager.

Intel, HP, SanDisk Ranked Best In Conflict Mineral Report

The Enough Project, part of the non-profit organization Center for American Progress, has released their second report ranking electronics companies by their use of conflict minerals. Conflict minerals, such as tin, tantalum, tungsten and gold, are used in nearly every electronic device and often their demand funds war groups in eastern Congo.  

The Enough Project hopes their report, “Taking Conflict Out of Consumer Gadgets: Company Rankings on Conflict Minerals 2012,” will help raise consumer awareness as well as encourage companies to further improve their efforts.

Intel moved up one spot, taking first place, followed by HP and SanDisk as the top three companies making the most effort to limit the use of conflict minerals. Also in the green—companies with 30% or higher progress towards responsible sourcing—are Microsoft and Apple, both companies more than doubling their score since 2010. Remaining at the bottom of the list, without any improvement since 2010, is Nintendo, which has made no known effort to trace or audit its supply chain.

The progress report measures improvement in three main areas: tracing, auditing and certification. Tracing involves following the supply chain in order to locate the mineral sources. Seven companies, starting with Apple, have made this information publically available, and thus provided a map for other electronics companies to follow. Auditing requires 3rd-party audits and getting certified means making a commitment to helping the communities near mines in the Congo.

There are also several areas that the Enough Project pinpoints as still needing improvement, including buying from conflict-free smelters, ensuring that all smelters are audited and encouraging other industries, such as jewelry, automotive and industrial machinery, to get involved. The report recognizes, however, that that improvements are largely attributed to direct consumer action, so pressure to improve other industries must be a joint effort between electronic companies and consumers.

United States legislation, fueled by consumer activism, is largely responsible for the rapid improvements over the past two years. The Dodd-Frank Wall Street Reform and Consumer Protection Act, signed by President Obama in 2010, requires companies that use tin, tungsten, tantalum or gold to trace the origins of these minerals and perform due diligence and audits if they originate in the Congo. Companies are already making large improvements to their mineral sourcing process even though the final rules of this new act have not been issued.

The Enough Project’s report is released just days before the Securities and Exchange Commission (SEC) upcoming vote on the rules for the conflict minerals law on August 22nd. “The SEC should ensure that retailers and all firms that use the minerals are covered by the rules and that there is not a long phase-in period,” said Sasha Lezhnev, co-author of the report and the Senior Policy Analyst for the Enough Project. “Otherwise, the Intels and HPs will be left unfairly holding the bag for a problem that belongs to thousands of companies that have been turning a blind eye to this problem for years.”
