Lite-On Europe has announced two new 20x "Super AllWrite" DVD writers, the world's first 20x DVD rewriter with Serial ATA interface, the LH-20A1S, and the world's first 20x external DVD rewriter, the LH-20A1PU. Here's part of their press release:

The LH-20A1S is an internal drive made for advanced computer enthusiasts. It incorporates, in addition to fast writing speed, a Serial ATA (SATA) interface. The SATA connection eliminates potential information and performance "bottlenecking " by offering at least 150 MB/s data transfer rate which should improve performance significantly compared with the Parallel ATA (PATA) connections you find on most current DVD rewriters. SATA also uses thinner data cables allowing better airflow to the LH-20A1S drive.

The LH-20A1PU is an external drive which can be enjoyed by both advanced and beginning computer enthusiasts. The LH-20A1PU features the Lite-On patented EZ-DUB technology which makes copying and storing of data possible with a single press of a button. The LH-20A1PU can be easily connected to your PC through a USB 2.0 connection.
The LH-20A1S will be available on the European market mid-February for € 49 including VAT. The LH-20A1P should hit store shelves shortly after for € 69 including VAT. More information, including a full list of specs, can be found on Lite-On's website.
