Seeking Replacement Drives for My Book Thunderbolt DUO

WD External and Portable SSD External SSD for macOS

I see that green dives are no longer in production, but my drive indicates to only use green.
Was there a update that allows for other drives like the blue, red, or black drives to be compatible at any capacity, or is there a limit?

I bought it around 6 years ago, for like $700. My Book Thunderbolt Duo which came with 2x2TB 3.5 Green power drives.
