    • CD-ROM : Audio CD ,CD-ROM , Mode 1 and Mode 2 ,Mixed Mode CD (Audio combined data) ,Video CD , CD-Extra ,CD-R ,CD-RW, CD-TEXT, Karaoke CD,I-trax, Photo CD
  • Reads discs of 8 and 12 cm in diameter
  • Data buffer: 512 KBytes
  • Data rate:
    • DVD Transfer Rate 16X max CAV21640 KBytes/s max
    • CD Transfer Rate 48X max CAV ~ 7200 KBytes/s max.
  • Access time:
    • DVD 105 ms typical
    • CD 85 ms typical
  • Weight: 1kg

Accessories: user manual, fastening bolts, CD audio cable, a diskette with drivers, a CD with drivers and a soft-DVD player (WinDVD). DDSS2 (Double Dynamic Suspension System) supported. Unfortunately, there is no an 80-conductor ATA/66/100 cable for connection to a respective controller. However, the tests show that it doesn't matter how the drive is connected - as UDMA/33 or UDMA/66/100. The front panel has two buttons for Audio CD playback - Open/Close/Stop and Play/Skip. The front panel also has a rubber layer which eliminates noise and protects from dust.

Test results

Quality of operation with CDs

CDWinBench 99

  • CDWinMark99 - 1560
  • CD-ROM Transfer Rate
    • Inside - 3090 kBytes/s
    • Outside - 6060 kBytes/s
  • CPU utilization - 9.11%
  • CD-ROM Access Time - 91.9 ms

Nero CD-Speed

The following information on the drive is obtained with the Drive check utility:

  • Vendor : ASUS
  • Product : DVD-ROM E616
  • Firmware version : 1.0
  • Buffer size : 512 KBytes
  • Maximum read speed : 8448 KBytes/sec (48 X)
  • CDDA accurate : yes
  • C2 pointers : yes
  • Speed settings : 6-8-10-12-14-16-18-20-22-26-28-30-32-34 X
  • Read RAW mode : yes

According to these data the drive supports all functions necessary for accurate capture of audio tracks. A list of speed modes is really striking. But the range of speeds is actually wider.

Noise characteristics.

  • Tray - 7/10
  • CD
    • Seek - 4/10
    • Total noise - 5/10
  • DVD
    • Seek - 4/10
    • Total noise - 6/10

At the maximum speed the noise level was acceptable. Unfortunately, there is no anymore a possibility to reduce a speed of operation with CDs with the Play button, though it is possible with the help of external programs (CDBremse, Nero DriveSpeed). Also, you can set any speed within the range of 2x and 6x to 48x.

DVD-Video playback with the Cyberlink PowerDVD 2.55

The DVD-Video was played without any problems; no artifacts were noticed. During changing the layer the DVD quality didn't get worse, although a layer changing time is quite big.


The drive is equipped with the DDSS2 system. When the drive worked with badly balanced CDs it didn't shine. The vibration was quite noticeable. Probably a speed growth adversely affected operation of the DDSS2.

Thermal conditions

There are no any complains about its thermal conditions, though I do not recommend you to install other devices tightly to its lower surface. The data were read after an intensive 2-hour operation:

T inside the case - 36°C
T of the upper surface - 41°C
T of the lower surface - 43°C

Possibility to make the drive region free (RPC-1).

According to www.firmware.fr.st, it is impossible to make this drive region free. However, there is one loophole. To nullify the zone changing meter you should turn off the computer and press and hold play/stop buttons. Then holding these buttons you should turn on your computer and wait until the BIOS finishes detecting hard drives and CD-DVD drives in the system. Then release the buttons. If you hold them too long the computer may hang. Then you should just reboot it.
