Even if you can crossflash to other models,
- you won’t gain any LightScribe capabilities of the 222 or 422 b/c the 122 has no LightScribe hardware.
- you may gain SmartErase feature from the 322 or 422.
If are just curious to see if it’s capable to crossflash between different models as a “fun” activity, that’s fine. But if you want to have the feature set of the particular drive, then getting that drive would’ve been a better option.
