Data Head Hunters don't know what it is. runs the programs needed quick enough for larger tasks, moves large files very well.  The best version in a long time. It is pushing for windows 11 , I tried those in Beta, I want to savor this as long as possible. Zero noticeable bugs. Great for traveling or private hideaway from the kids. Hook it to TV or monitor your set in seconds. you see in photo a hub makes it possible for a lot of attachments, and pushes them without getting hot. Oh! and no noise.
