Bought 3 units of 32GB. Windows recognized 32GB of free space and was able to write an 8GB file, but I found the write speed to be very slow. When formatted for use on a Linux system only 4GB was available, it was switched back to Windows and reformatted with NTFS and couldn't get more than 4GB. All three devices behave exactly the same. I think they use some kind of hard drive to "mask" 32GB of storage and use high compression software on the data. I wouldn't recommend it, waste of time trying to figure out why the data couldn't be written.
