Mikhailtech has posted a review on the Lite-On LTR-52246S 52/24/52 CD-RW Drive
SMART-X will also kick in if you are watching a movie from a CD (VCD). In this case, you don't need the CD to be read at full speed, so SMART-X will adjust speed for optimal performance. The SMART-X function will also check for scratched CDs and slows the drive down to prevent reading errors, so it acts almost like an error detection and correction mechanism. SMART-BURN is short for Smart Monitoring & Adapting Recording Technology for BURNing. It is not just a buffer underrun protection technology, it also acts like a writing error reduction system to assure the best quality write available. LITE-ON merged media condition checks, variable writing speed strategies, OPC (Optical Power Calibration) tests and buffer underrun technology. The drive has a media list and writing strategy in the firmware, and when a media is inserted the SMART-BURN checks to see if the media is found in the firmware. If so, then the preset writing strategy will be used. If the writing strategy for the inserted media is not in the firmware, a default strategy will be used. This includes a series of media condition checks, OPC (Optical Power Calibration). The drive will choose the best laser power and speed for the inserted media, or it might even use variable writing speed strategies. It is just like having both Plextor's BURN-Proof and PowerRec in one complete function, thanks to LITE-ON and MediaTek.Read more
