Some new information on Toshiba-Samsung SH-S182D a.k.a. TS-H652.
The drive is a new, refreshed design, not just a firmware-based improvement.
It is going to use a new optical pickup from Sony with a higher-power (27 mW) Sharp laser diode, and a new, faster spindle motor from either Samsung itself or Nidec Japan. Because of the faster motor, power consumption will go up by 2-3 Watts, or about 0.2 A on the 12V line.
This drive is currently promised to be available for sale in June. We'll see.
DVD burn times are sub-five minutes, so it should beat the current records held by 16x Hitachi-LG Renesas drives by a good 20+ seconds. Its 18x times should also be almost a minute faster than Plextor PX-760A's 18x times.
I will be buying one of these!
