Patriot Stellar 32GB USB 3.0/USB OTG Flash Drive For Android Tablets and Smartphones - Up To 140MB/s Transfer Speeds

These flash drives are one of the cleverest ideas I've seen in quite a while. I have both an Android phone and a tablet, and it's sometimes a nuisance to have to use Cloud storage to transfer files back and forth between them and the PC. This is a much faster and easier way to transfer large files, like videos or music collections, to an Android. The small size makes it easy to play videos straight off the flash drive as well. Much handier than using an OTG cable and a regular flash drive. I also use my tablet for serious writing, and it's important to be able to back up data, whether I have Wi-Fi access at the moment or not.I purchased both the 16 and 32 GB sizes. The 16 holds 15.5GB, and the 32 shows 28.8GB available. All flash drives tend to round up, and seldom have their stated size actually available, so that's normal. Both the standard and micro USB connectors work properly. My laptop doesn't have USB 3 capability, so I can't verify the read/write speeds. They do seem a bit faster than my old USB 2 flash drive.Important Note: The packaging says "Android 4.0 Required", but that doesn't tell the whole story. Your Android device also has to have the hardware required to act as a USB Hub. The fact that your device can charge through the USB micro port does NOT mean that your device can act as a host, or power another device using the Android battery. Your Android device also has to have the software to be able to mount USB Flash drives, and have some sort of file manager to let you Copy, Delete and otherwise manage the files on the Flash drive.For example, my Samsung Galaxy S3 recognized the Flash drive as soon as it was plugged in. Yeah, Samsung!! My Google Nexus 7 (2013), although it has the hardware to act as a USB Host, has that feature disabled. You have to buy an App from Google to be able to read files from a Flash drive. Grrr. And the official Google App will only read media files, and won't let you write to the Flash drive at all. Double Grrr. I had to Root my Nexus, and install an App called "StickMount" in order to be able have full read/write access to the Flash drive.So you need you to make sure your Android device is physically capable of using a Flash drive. Even then, be aware that certain companies, like Google, may have turned off that feature in their version of the device. If the feature is just turned off, it will usually require rooting the Android device, which voids your warranty, in order to turn the feature back on.

I bought this after doing tons of research on MicroUSB drives for mobile phones. I have a Note 5 and had no problems inserting it in (its OTG compatible out of the box). I transferred roughly 28 files - mostly photos and a few videos totaling 158 MB - so nothing to large. I used ES File Explorer Pro as it has a more robust interface than Samsungs my files app. Transfer/Write speed averaged 4.5MB~9MB per second - well below what is advertised!When trying to insert it into my PC's USB, i had to use quite a bit of force, and even heard a scratching sound. I pulled it out to see that part of the color had come off. Apparently its slightly oversized. I tried this on 2 different laptops and both had the same result.I would say buy at your own risk - if its for your phone only then you should be fine (again if its OTG Compatible.) I wouldn't recommend if you want to quickly plug into your laptop and back to your phone.

I'm using mine to store and to later transfer, large files like movies and videos, from my desktop computer to my Nexus 7 (2013) tablet. It's well built and with an excellent transfer speed. I love the dual design (USB 3 on one side, micro OTG on the other). Note that this is quite small (about 1/3 the size of your little finger) and the USB side does not have a cover. I store mine in a tiny Ziploc. Also, you will need an app like Nexus Media Importer for it to work on your Nexus 7. The app cost me $3.99 ... a great investment to give your Nexus 7 (or most other Android tablets) unlimited storage capacity.BUT ... I bought my 32GB for $20.99. A few weeks later I went to buy another one and they had raised the price to $29.99. I felt they got greedy and didn't buy the second one. You can beat their greediness by purchasing an "Importer 520 USB A Male to Micro USB Female Convert Adapter" for about $1.99 and than buy any micro USB OTG flash drive (which should be less expensive).

Ive had this drive for a couple of months now, so this is a short-term review. So far this drive has worked flawlessly, and works really well with my Galaxy Note 2. I transfer files a lot throughout the day, as my day job is an IT support technician for small businesses. I really like the size of thise drive, as it will fit anywhere there is an open USB slot.My only gripe so far is that the drive doesnt have an LED on it to let you know when its transferring data. As long as you are accustomed to removing your USB drives the correct way (going through the procedure of ejecting it properly within whatever OS you are using) this isn't much of an issue, but it would still be nice to have a small LED added in the future.Im giving it 4 stars for now because I havent had it long enough to see how it will perform in the long run, and because I feel that it needs an LED to indicate when it's reading or writing data.

Great flash drive. Fast, small, easy to plug in and easy to take out. There are many other combined USB/MicroUSB drives out there that went too small... they're hard to get out.This Patriot is the perfect size, and the cap is not easily lost on the microUSB side. With a little app I used this guy in my Galaxy Nexus, Nexus 7, and Nexus 5.It feels plastic, it doesn't seem like a metal, but I think it may be metal... it's shown some pretty noticable wear on the full-USB end. I'll post some pictures so you can see. This does not affect the drive at all. I have been using it in a number of brand new computers with rather 'tight' USB ports.It's served me well for a couple months now with some pretty regular use. My only recommendation is that you make sure you "eject" the drive from your OS as a habit. This drive seemed more "robust" than my other high-capacity flash drives in this regard, but I did manage to almost kill it once by just pulling it.

Arrived fairly promptly - purchased to increase the storage capacity on my Moto G phone, which it does, but it sticks out at the bottom of the phone , so is of limited use out and about unless you have somewhere safe to put it.

Its super quick, true usb 3.0 write/read transfers.Its so tiny u can lose it if you blink. It has otg, but coudnt use it in my nexus 4, most probably phone fault.

Velocità misurata in lettura su usb3.0 113,5 MB/s e in scrittura 20,57 MB/s. Sul mio sistema più di tanto non fà, anche se sono velocità del tutto rispettabili.Di ottimo ha che la presa microusb da inserire nel telefono è leggermente più lunga di altre penne simili e non devo togliere la custodia al tel per usarla.
