So it's 64 GB and mobile. That's pretty cool. The idea of it being hot swappable between android and windows is awesome. It's a little outdated since it's using micro usb, but aside from that it's great!

Well, I have 4 of these Ultra Dual Drives, they all look identical, three are 128 GB in size, and one is 64 GB. They all work ok, no issues with the sliding thingy's but my use has been in a clean environment. Problem are the 128 GB drives, They seems to have gone through a hardware revision. The new revision is slower than the old, The old drive peaks at 175 MB'sec in crystal diskmark, whilst the new drives peak at 134 MB'sec, they are overall much slower.

It fits into the charging port of your phone or USB port of your PC. You will need a File Manager App.for transfer, and your Storage App for dismounting it. Pretty easy 4 sequence pasting, moving/ copying material from devices to this flash drive or other devices. Stores hundreds of videos and documents or a thousand photos. I have a few these flashdrives labeled. I only load a couple hundred items in each to make finding items more manageable. I also have a Case Logic case for them, with a garbinger hook, that I always hang in the same spot. This case stores 4 flash drives and is recommended, as these flashdrives are fairly tiny and easy to misplace.

I bought this so I can access files on any of my device i.e. PC, tablet and Android phone and it does this well. You can slide it out an expose either male connector and plug it into the relevant socket on whatever device you have. I found it works fine on Android (Samsung and Motorolla phones) it is readily detected and accessed, of course you still need the relevant software on your device but this hasn't proved an issue for me. It also works fine on the Windows 10 tablet and PC. The tablet also having the smaller USB socket. A few slight quibles.... You notice it gets warm when left it, not hot but definately warm which I have not experienced on other USB drives. It can be a bit fiddley to slide the end out.

The casing on my previous one broke quite readily, the thing still worked well enough without a casing but hell it cost me 20 ! In work we have now switched on bitlocker so any USB's have to be bitlocked and this stops it being used on Android or indeed any OS but windows, so two weeks after forking out 20 I stopped using it !!
Passes read & write test to every sector using H2TestW. Has fast read & write tests using CrystalDiskMark benchmark. Product appears 100% Genuine! Awesome small size factor. I just tested it on my phone too. No problems working on an old Samsung Galaxy S4. Just copied a movie to the flashdrive and can run it straight from the flash drive on the phone just fine. Highly reccomended!
I am a great fan of Sandisk products and already owned two flash drives before I purchase this one. However I must inform you that I am very disappointed with this product whose quality is very poor. 1. Whenever you adjust the usb pin or the mini usb pin, it does not lock properly and when you try to put in the corresponding port, the pin just slides back inside. It is very difficult to plug the drive in a port. The locking device does not work properly. Very poorly designed. 2. I have tried the dual drive in three devices I own; a Samsung Tab 3 Lite, a Samsung Tab 4 and Samsung S4 mini. In any of the three devices, the dual usb drive is NOT detected. The USB flash therefore can be only used as a storing device. I am very sorry that I have sent good feedback on the ... MoreI am a great fan of Sandisk products and already owned two flash drives before I purchase this one.

I work a job that mostly requires me to sit around and do a whole lot of nothing. I have my DVR at home set up to record TV shows straight to a hard drive in my media center, which is a computer with 5 terabytes of storage that also includes all of my CDs, DVDs, and Blu-rays ripped to it as well. I used to download stuff from that setup to my tablet at work. Problem is, there's no wifi there, and T-Mobile doesnt offer an unlimited data plan for tablets. However, I have their Truly Unlimited plan on my phone. I used to use my phone as a hotspot to download my stuff to my tablet. But, recently T-Mobile decided to crack down on that and tell me I couldn't use my UNLIMITED data the way I wanted. So, I needed a new solution. I used to have an OTG cable way back when it ... MoreI work a job that mostly requires me to sit around and do a whole lot of nothing.

But, recently T-Mobile decided to crack down on that and tell me I couldn't use my UNLIMITED data the way I wanted. So, I needed a new solution. I used to have an OTG cable way back when it was first implemented, but I tossed it out because at that time OTG was still buggy and ill-implemented. However, recently I'd been seeing and hearing more and more about how great it is, especially on Android Lollipop. So, I decided to give it another shot. Now I download my stuff through my phone, put it on the drive, and I can then plug into my tablet to enjoy it. I couldn't be happier, and it saves battery too, since I don't need wifi on my tablet and the hotspot on my phone.
I would've given it a 5 but it already fell apart on me. I did manage to stick the little plastic casing back together and it is working again like a trouper but it is extremely delicate. I will say I like the option of being able to use it on my tablet or my computer but they really need to make them out of some tougher material....the shell is sooooo delicate. I had it plugged into the back of my tv and when I went to unplug it ended up with the case falling apart. However, it split at the seams so was able to put it back together and the little drive keeps working. It is also tiny so if you are expecting something the size of a regular stick, forget it. This thing might be the size of the width of a quarter approximately. Super easy to transport in your pocket or ... MoreI would've given it a 5 but it already fell apart on me.

All and all, I am ok with my purchase. Have gotten so many fake drives that read fake capacities on eBay that was extremely happy to finally get one that wasn't fake capacity.
I've stated before that I have an enduring belief AND trust in ALL SanDisk USB Flash Memory drives. I've been using them for more than a dozen years now, and have never had a single device failure.These SanDisk - Ultra Dual 32GB (and 64GB) USB 3.0 Type A/micro USB Flash Drives are the best way to quickly expand the "on-board" memory of any tablet OR smart phone that has a "universal" Micro USB data (and charging) port. The sliding USB connectors design (type A on one end and micro USB on the other) is really quite solid and does lock in place at either end of its sliding range.I really have made great use of the ability to load data, media and program files onto these drives using my laptops and then transporting the loaded files straight to my tablets.

These drives are really handy and easily portable through ALL phases and places of your everyday life.MY BEST SUGGESTION REGARDING THESE MINI FLASH DRIVES IS: ... Because these flash drives are SO small (especially with the connectors retracted completely), I REALLY DO HIGHLY RECOMMEND attaching a 16 - 20" lanyard to help keep it from getting lost deep in the pockets of your "computer's" carrying case/bag! - It has a strong chromed "bar" wrapped around the center of its body that will easily allow you to attach a lanyard or a small spring clip or a small "split" key ring that you can attach a fob or other strap to.
I purchased a Ultra Dual Drive USB 3.0 couple of years ago. And now it had automatically became Write protected and shows Read only. There is no any button to enable it and tried all solutions and didn't work Please find me a solution.32GB USB
