By SanDisk has made another nice revision to their Ultra Dual USB Drive, a small micro-USB stick that you can use to quickly transfer files between mobile devices and computers. This is version 3.0, and the main changes SanDisk prides themselves on are USB 3.0 support (for the portion that allows you to transfer files from the stick to a PC, anyway), faster transfer times in general, and an improved micro-USB connector that’s been lengthened to ensure it’ll work better with cases.
Returning is the retraction function that allows you to quickly switch between the full-sized USB port for use with PC and the micro-USB port for use with your mobile devices. The flash drive will be available in configurations of either 16GB, 32GB or 64GB, with the low and high end of those priced at $22.99 and $64.99, respectively.
Need a quick idea on what to expect should you opt for one? The video above is embedded for that very reason, so be sure to give it a quick viewing (30 seconds long) if you’re wondering just what it is these are used for.
All this is great, but semi-useless since Google prohibited writing files to sdcard_ext with a file manager.
By the way, the best storage expansion option I’ve had so far is a little Monoprice’s dongle that has a microUSB on one end, and regular USB on the other, and a regular microSD card slides inside the regular USB jack. Best of 3 worlds – PC, Nexus(no SD card), and SD card equipped devices. And it only costs like $5.
This will work out the box on the HTC One, and most Galaxy devices. If you have a Nexus device, you will need root and a handy app called Stick mount to take full advantage of this.
There are some file managers that will support it without an extra app, at least on a Nexus device.
Yep. There’s a few ways to get around this (most require root). Another way is to install the file manager app as a system app, which will usually give it the rights it needs to manipulate the sdcard.
Root explorer, has a way to write to external storage without ROOT. It takes advantage of the revised SD card rules on lollipop.
