UGeek heeft een review gepost van een 50 speed Kenwood drive met TrueX technology:
The Kenwood 52x CD-ROM drive is truly an amazing drive. It uses TrueX technology from Zen Research which splits a single larger than normal laser into seven separate beams. Each of these beams is used to read a track of data from the CD-ROM.
This multi-beam technology allows the drive to spin at lower rates than other drives, yet still read data faster than any of them. The drive spins at between 1850 and 4750 RPM using CLV (Constant Linear Velocity) technology, like most CD-ROM drives before 16x speeds used. This technology spins the disk faster when the drive is reading data towards the center of the CD and slower as it reads data towards the edge.
