The last USB 3.0 OTG flash drives we have tested were sporting a smaller footprint and also needed extra protective covers for avoiding damages to their connectors. In this case, the chassis is indeed bigger but no extra accessories are needed, while we can switch from one interface to another just by working with the slider.
At first we would like to thank Lexar for sending out a sample of their latest M20 Mobile USB 3.0 Flash Drive for testing and reviewing.

Transfer and share files between your Android tablet and smartphone without cables or Wi-Fi
No more searching for hotspots, draining your data plan, or toting clumsy cables with you on the go. The Lexar JumpDrive M20 Mobile USB 3.0 flash drive lets you move files between your On-The-Go (OTG)-enabled Android devices, or from device to computer—no data connection or power required.*
Store and share content faster
The drive leverages USB 3.0 performance with up to 120MB/s read transfer speeds.** You can quickly transfer a 3GB HD video clip in less than one minute—compared to the 4 minutes it takes using a standard USB 2.0 drive.*** And for added versatility, the drive is also backwards compatible with USB 2.0 devices.
Increase storage and back up files
With capacities from 16GB to 64GB, the drive also lets you offload lots of content from your tablet or smartphone to create more room, and also provides a great way to back up files. You can also download a file management app like ASTRO File Manager from the Google Play™ store to quickly and easily manage files from the cloud and mobile devices.
Enjoy easy connectivity
Faster and more convenient than using Wi-Fi or data connectivity, the USB On-The-Go capabilities of the high-performance Lexar JumpDrive M20 Mobile allow you to easily transfer, store, and swap files between your tablet and smartphone for ultimate convenience, wherever you may be.
Convenient portability with retractable design
This 2-in-1 drive sports a thumb slide design, with a connector on each end—micro-USB and USB 3.0—that both retract. This makes it easy to carry and means there are no caps to lose.

Here we have another Lexar USB 3.0 Flash Drive product in our labs, this time the M20 mobile, which also sports OTG features. The retail packaging is really simple and shows us on the top side the total storage capacity, rated speeds and some other useful information:
On the back side we can check some words related to warranty, in multiple languages:
As the previous Lexar products, we are dealing with an overall professional look of the M20 chassis and its design does not imply the use of an extra port cover. By adjusting the blue slider, we can make accessible the OTG connector, the USB 3.0 connector or have both connectors protected at the same time. On the top side of the unit we have the total capacity written along with the manufacturer logo:
Near the OTG connector we also have a small area where we can attach a lanyard of our choice (not included inside the original packaging):
On the back side we will be able to check out some code names:
Here is also a shot with the USB 3.0 connector ready for use:
The testbench was composed from the following hardware:
CPU: Intel I5 3570K Retail @ stock
Motherboard: Z77 OC Formula
RAM: GeIL Black Dragon 2x4GB DDR2133 (@1600)
Video: Sparkle GTX 470 with stock and OMNI A.L.C.
Power Supply: Nexus RX-8500 850W modular
HDD: Seagate Barracuda 500GB 7200.11 & OCZ Vertex 4 240GB SSD
Case: Thermaltake Armor+ LCS, stock cooling
OS: Windows 7 Ultimate x64
The Lexar JumpDrive M20 OTG 3.0 Flash Drive has arrived formatted FAT32:
To determine the flash drive read speeds, the HD Tune v5 utility was used:
To measure the real life performance, we have used the Total Commander application to copy to the flash drive and from the flash drive the same file and recorded the transfer speeds, after they have stabilized.

We have also performed some extra tests with this drive and the results can be checked out right here:
The last USB 3.0 OTG flash drives we have tested were sporting a smaller footprint and also needed extra protective covers for avoiding damages to their connectors. In this case, the chassis is indeed bigger but no extra accessories are needed, while we can switch from one interface to another just by working with the slider.
Regarding the product performances, we are dealing with decent read speeds and mediocre writes when having the M20 connected to our PC, but these are more than enough for the OTG interface which is limited to USB 2.0 speeds.
For an OTG product, we find that the M20 32GB has a fair price of 12.6 Euros, while the smaller, 16GB version can be found online for just 9 Euros.
We would like to thank again to Lexar for making this review possible!
