While the BenQ DW1640 was the best all-around burner/reader/ripper ever made, the Sony DRU-V204A (Optiarc AD-7200A) was probably the best pure burner. This drive marked the end of the line for IDE burners as a viable option. After this was discontinued, quality IDE burners no longer existed, and people were forced to switch to SATA.
This drive will still outperform any SATA drive in terms of burning quality, except for maybe the Pioneer DVR-215D and Samsung SH-S243N (and those are discontinued as well).
