ASUS recently announced two new 20x DVD writers, the DRW-20B1S and DRW-20B1ST. Along with 20x DVD±R, 12x DVD±R DL and 12x DVD-RAM writing speeds, these drives feature ASUS's new Optimal Tuning Strategy (OTS) technology. According to ASUS's press release, OTS automatically adjusts the burning strategy to deliver the best possible write quality.

Catering to users that demand increased data storage, ASUS, a leading provider of high-performance optical storage devices, today announced the new DRW-20B1S/B1ST - an industry leading DVD rewriter that supports 12X DVD-RAM write, 20X DVD+/-R and 12X DVD+/-R double layer media sources. It also features Optimal Tuning Strategy - a technology that automatically adjusts burning for optimum disc backups; and E-Green Engine for great energy savings.

The ASUS DRW-20B1S/B1ST is equipped with an innovative feature - Optimal Tuning Strategy (OTS) that provides users with improved disc burning for better total write quality. With OTS, the drive will perform a test burning before really burning the disc, and OTS is intelligent enough to encompass both media and drive variations, as well as operating temperatures into its calculations - allowing it to provide the optimal write speeds to produce the optimal burning strategy for the new disc. After the disc is burnt, OTS memorizes the particular type of disc, and will utilize the same burning strategy when the same type of disc is used. This not only reduces the possibility to burn unplayable discs, it also provides high quality backups and improves compatibility so that the disc can more easily be read by other drives; as well as extends the lifetime of drives.
