Each group (separated by blank lines) represents rebadges of the same drive (i.e., the first firmware letter is the same). This is as complete of a list as I am able to get. There are a few newer (and a few older) drives that I couldn’t confirm. Contributions are welcome. Please be as precise as possible with the name–exact capitalization, puncuation, and internal whitespacing (because this is the list that OP2 uses, precision would be greatly appreciated ;)).
Edit: The list now has its own website
