My Passport Wireless PRO 3T!

I have a few questions:

  1. Can i defragment the “HDD” even when the windows is recognize as SSD?
  2. What ever i copy on it the max write speed is 40MB/s through USB3.1. Is that an issue or thats the limit of the hardware? I have also a HDD My Elements and the max speed is between 100-70 MB/s!!!
  3. How come that im buying a “new” My Passport Wireless PRO 3T and when im doing some test and i found out that:
    a) Power Cycle Count: 1746 counts
    b) Power On Hours: 259d 8h
    Conclusion is that you are selling used HDD for barnd new prices???
