The DDU1622 differs from the above-described DDU1615 in having a white-colored front panel and an audio output with a volume control under the tray, next to the Eject button. And there are also no deep grooves in the top panel. The rear view is slightly different, too. We’ve got the same analog and digital audio outputs, power and interface connectors, and two jumpers there, but the factory testing jumper is placed on the right rather than on the left, as usual.
The technical characteristics of the Sony DDU1622 are overall similar to those of the DDU1615 model. The drive can read DVDs at 16x and CDs at 48x speed. Like in the previous case, you have to press and hold the Eject button for a few seconds with a disc inserted to use the maximum CD reading speed. By default, CD media are read at up to 40x speeds. The average access time is 85 milliseconds for CDs and 100 milliseconds for DVDs. The buffer is 512 kilobytes big. The drive supports the following media formats: DVD-ROM, DVD-R, DVD-Video (DVD-5, DVD-9, DVD-10), Audio CD, CD-ROM (mode 1, mode 2), CD-ROM/XA (mode 1, mode 2), Video CD, CD Extra, CD-R, CD-RW. The dimensions of the device are 41.4x146x176mm; its weight is 0.8kg.
The average retail price of the drive is $24.
