Silicon Power X31 16GB Android Dual USB Flash Drive, Silver/Black (SP016GBUF3X31V1K)

This little device is a another awesome 'Silicon Power' product. It very very tiny, well constructed & nicely designed.Pros: Very very good read speed (sequential read speed: 114.4 MB/s) & good write speed (sequential write speed: 21.36 MB/s), very good build quality & design.Cons: Nothing!Conclusion: A much better solution for all android user than microSD card. Those who going to buy the new Samsung Galaxy S6 or S6 Edge, this is a must have device for them. You can transfer your contents, backup your photos & videos easily to your PC or laptop.Highly recommend this OTG drive.

One of my biggest frustrations with newer versions of android is it's a pain to transfer data between your phone and your computer unless you're dealing specifically with your camera directory. My first experience with this type of product was Kingston's OTG which worked well but the shape/design of the device didn't work with my case and when plugged in I couldn't lay my phone flat on it's back because the cap for the drive stuck out the side. This SP X31 solves all of those problems. The design of this device works perfectly with my case and I can't see it being an issue with many others either as the microUSB connector on it is longer and allows come clearance but even with the longer connector the whole drive is very tiny and I can leave it plugged in without it getting in my way of using my phone. Performance wise the copy speed is slightly better than the Kingston and on par with any other USB drive I've used and on my computer it's certainly running at USB 3.0 as it's faster than any 2.0 drive I've used.

It absolutely works as advertised, Nexus5, Android 5+, Nexus Media Importer, works fine. If I had anything to say, it may actually be too small!I can see losing this, I put a small lanyard on it that I had, it has a tiny hole for one. I also am using a USB silicone tip cover on the standard end when it's exposed, and carry it like that, the micro end is swiveled in. Trying to avoid lint or debris getting in the USB plug end.It's really impressive how the memory media is integrated into the standard USB end, it's the part that is usually the plastic alignment tab.I'd like to find one of these that has a more conventional USB thumbdrive form, each end is a connector, each end has a cover. I think it would be easier to keep track of. I once had a tiny USB drive made for a keychain use, had a built - on tether. One day it was gone, broken tether. There's a practical limit to how small some things need to be, or how to use them.

It's hard to believe how small this thing is and that it can also be used as both a standard USB stick and as a USB stick for Android phones, as external storage! You can spin the black part of this device around to switch which input you're using. Unfortunately, I found it to be a little bit flaky while on my old Android phone, and it also doesn't natively work with an iOS device (doesn't have a Lightning plug), but it's still pretty cool and impressive that it can store 32 GB in a form factor like that.

These are so cool. I use my phone as a camera and I used to dread having to hook it up to my laptop to get the pics off for editing. This USB flash drive is the perfect solution. I've been using it for months almost daily with zero issues or problems. Every device I've used it with instantly recognizes it and quickly reads or writes to it. The only thing I'd add as an improvement would be to be able to attach some sort of lanyard to the drive as it is tiny and could be easy to misplace for those of us with less than perfect mental focus. :)

Good capacity, works well, and is fast. Only problem I have is that on some computers (particularly Dell's, anecdotally), this USB product shorts the computer out... so when I insert the USB drive into the computer, and sometimes when I remove the USB drive from the computer, somehow power is cut to the computer, like someone flicked the power off.https://youtu.be/OY0BedKqmDk

We were not able to get the android phone to 'see' it. There are directions on how to do this step, but neither my son nor I were able to use the device. We are both very PC literate, having experience on Windows PC's even as extensive as wiping the hard drive and starting over from scratch. Yet, we each went through the directions step by step, and -- nothing ?? I think the device is OK, but the instructions are not very clear.

Attractive design. Body looks pretty solid and sturdy. There is a hole in the plastic part for attaching a cord. USB 3.0 writing/reading speeds. Works great as OTG with Samsung S4, Toshiba Encore tablet and Toshiba Laptop. NO issues. Delivered in time. Great product.
