The M5 Pro Xtreme package is a nice shiny design that is nearly identical to the original M5 Pro. Xtreme branding was applied as you can see.
Plextor lists performance specifications on the back of the box along with a feature list.
The inner packaging has a nice design with the drive kept away from the other hardware components so they aren't scratched in transport.
Here we see the accessory package all laid out. You get a desktop adapter bracket, screws and a pair of paper manuals. Our drive arrived used by another site and didn't include a software disk, something we normally see.
