Best would be subjective, but as a minimum, the drive needs to be compatible with Macs.
Here are a few, not necessarily in any order, that you may want to further research to see which one best meets your requirements for this drive. I also suggest that you double-check the store's return policy should the drive not work out for you.
- LG GP65NB60 Ultra Slim Portable DVD Writer
- Asus ZenDrive U9M
- Pioneer BDR-XD07S
- Dell DW316 External USB Slim DVD R/W Drive
- OWC Mercury Pro External Optical Drive
Note: Ensure the drive supports USB 3.0 or USB-C for best performance with Apple Silicon Macs.
