To view comments left on Amazon, many users are disappointed with the new generation of WD My Passport Essential drives when they were satisfied with the old.
This is the old version with the mini USB socket and WD Sync with the software; I did not have unstable connections issue and I removed the WD Sync software easily and the drive becomes a simple use a USB key.
This is a good, reliable, lightweight, that fits in a pocket, easy to use, quiet, not too expensive ... I recommend it without hesitation.
