I've had the 16 GB model for a whole year now. I maintain a repository of active documents in a variety of forms. A large number of little files occupy up a third of the flash disk. The flash drive has been used without incident. The sliding mechanism performed admirably throughout its operation. The damaged flash drive now works perfectly. When it comes to 4-ku, I find that Sandisk's sliding mechanism is the gold standard. I would suggest it generally.
