All reading speeds are in constant angular velocity unless otherwise indicated.
"?" indicates that the format is supported, but the speed specification is unknown for this model.
Functionality not listed in "Additional functionality" (e.g. CD-MRW support) for a particular model does not always imply that the feature is missing, but may also imply that existing sources have not confirmed that feature for that particular model yet.
Half-height
Model numbers with the third digit being a "2" stands for a Parallel ATA + Integrated drive electronics (IDE) interface, while the digit "3" stands for a Serial ATA (SATA) interface. DVD writers by TSST may have a "WriteMaster" branding.

Some models such as the SH-S162 and the SH-S182 have "L" variants (SH-S162L and SH-S182L) respectively, which indicates support for LightScribe technology.
Writing speeds higher than ×16 (constant angular velocity) are only unlocked on quality recordable media from selected manufacturers, including Mitsubishi/Verbatim and Taiyo Yuden.
Slim type
On slim type optical drives, accessing speeds are physically limited by the rotation speeds of the engine rather than the performance of the optical pickup system or the physical strength of the disc.
