The B2 has an SD Card - typically 8GB or 16GB - which holds the operating software. The B2 loads this each time you power it on - the red and green LEDs flash alternatively to indicate this is happening. The only time music is stored on the SD Card is when Aux In mode is used to record (personally, I have never done this intentionally, but I have seen a small number of GB used on it with none of the 480GB on the SSD used. Probably when I was in confusion.)
Currently we refer to, and the menus show HDD or Hard Disk but this really means HDD or SSD.
All B2s have a SD card, the main purpose of which is to hold the operating system. For the main music storage, they also have either a HDD (hard disk) or SSD (solid state) drive. Some newer B2s do have SSDs, but I seem to remember that the larger capacity new ones still use HDDs. No matter, there is always one card and one drive."

Finally, after trying to carefully figure out all of the information I thought was relevant to my initial project
i.e. A desire to copy to my restored 2010 JB7, in WAV, all the music files held on my B2 SSD (as FLAC).
I thought that , in theory, at least, would be to:
on the B2, in Settings/Compression/ Select FLAC, FLAC + MP3...............or none (WAV)
