I have, amongst other things, an Acer Chromebook which I really love but it is a bit tight on storage at 16GB. I know that Google wants me to store everything in the cloud but that just isn’t possible when you are disconnected and want to watch a movie.
My requirement was to have something with a reasonable amount of storage but didn’t stick out too far from the machine so I could leave it connected all the time. I somehow stumbled upon this
Micro SD USB Card Reader adaptor which pretty much does what it says on the tin.
I shoved in an existing 64gb micro SD card that I had and put it into my laptop and was able to play movies and music without any issues and not dropping or lag. I know that there are USB drives which are similar in size and capacity but if you have a Micro SD card kicking around unused then this could be just what you are looking for.
UPDATE! SInce I wrote this I notice that 7dayshop is selling this 32gb card complete with a USB 3.0 card reader for only £12.99. So if you want to try this out now might be the time.
