There was a problem filtering reviews right now. Please try again later.
As for people's opinions on speed, ie. read & write speeds, they really don't matter when you compare the different drives like this. They mostly depend on the device being used & if that has the ability to transfer quickly.
I like the simplicity of this "slide" that protects the two port ends. The last one that I bought (different style) had a similar plastic cover that protected the connection ports, but just a few weeks into using it the other drive's shell broke & left me with just the internal ports exposed, eventually the micro port broke. That's why I bought another, I hope that this outer shell lasts longer than the other one did. I expect this should last me quite a few years, like the other did, I just hope it retains its outer shell.
I own and love an Amazon Fire HD6 but find I am constantly fighting its memory limitations (only 8GB net of the operating system) when I travel.
With this device I just create a personal library of my personal digital content (pictures, videos, mp3, etc by copying it from my computer, using the standard USB plug -- just like any USB flash drive -- and if you have a USB 3.0 port the transfer is very fast. Then, when I want to watch content not available online I just plug the micro-USB side into an Android device and access all the content.
On the Fire HD6 I first needed to load a File Manager App (I used ES File Explorer) to access the files, and that enabled me to watch videos with any media player I had available (of which there are many - I've been particularly enjoying MX Player and VLC Player). I can also copy content from the drive to my device's memory (in the DCIM folder) which enables me to access it without the USB drive attached. This is useful on a long plane ride when you will probably need to plug a charger or external battery in at some point while still watching content. And you can copy content from the device to the drive and then remove it from the device to free up space.
Note -- the only thing I haven't been able to make work is using the device for application-integrated content such as downloaded videos in Amazon or Netflix or downloaded music in Amazon Music. I can neither figure out a way to get my device to recognize the drive in order to directly download the content to it (as is possible with integrated expandable microSD storage), nor to work if I copy downloaded files from the device to the drive, to temporarily free up storage (I tried this once but it messed up my device's internal accounting of available storage so I had to re-initialize the device.). However, this is a minor issue -- I have more than enough personally owned digital content to provide an wide variety of entertainment while traveling unconnected or otherwise poor wifi connectivity (as I've discovered can occur during peak holiday times even in places with usually good connectivity when everyone is trying to use them to watch videos).
I recommend purchasing the largest available version (256GB) so I don't have to think about which content to take in advance -- I just maintain a fairly large library of videos and music for use whenever the occasion arises.
