DVD+R DL 4x
I don't know if the specs from PC Home are right, especially since this is most likely based on the Lite-On SOHW-1673S. If so, the drive should have 48x CD read and write and 16x DVD-ROM read.
I've already asked Sony America when their 16x16 drive was going to be released. All they said was soon.
