Sumicom S600 is Loud
Who would have ever thought such a small box could be so loud. This is mainly because I have an old Western Digital WD120BB in it and it sounds like a vacuum cleaner. So, the next step is a $105 investment in an ultraquiet hard drive. These are mainly identical, so I mainly shopped by warranty. The Samsung has a three year warranty for about $5 more than the Western Digital or Seagate models...

I also need a 2.5" to 3.5" adapter so I'll order two because shipping is the big charge and "Cables for Less":https://www.tongfamily.com/guide/pcs/2005/01/09/25_to_35_hard_drive_adapter.html has them.
