I have a 128 GB ADATA flash stick model UV128 which is very slow.
On plugging the stick into a USB port, it literally takes several minutes before it is fully recognized by a computer (tried stick in two different computers) and then shows the stick contents!
Writing and reading data to/from the stick is also very slow. Small files of around 4 MB literally takes about 2 minutes to write, and reading has similar time.
I'm currently doing a full format of the stick (using NTFS). But as of this writing, the format is only 1/3 complete after about 15 or so hours of formatting!
I strongly suspect that this stick is faulty (and/or has a very slow controller embedded), as my other USB sticks (64 GB and less) are almost immediately recognized by computers upon insertion of the sticks into USB ports. And writing and reading data to /from these other USB sticks is much faster (taking just some seconds to process around 4 MB files).
Although the suspect ADATA USB stick is very slow, it does eventually write and read data successfully. However, due to its slow speed I'm seriously considering throwing this stick out and getting another (brand) as a replacement.
