Subjective Comments
52X CD read / write
Mostly air turbulence and a bit of motor whine
24X CD read / write
Smooth subdued air turbulence sound
CD play (Windows Media Player)
Quiet steady whirring
Positioning noise
Subdued damped clicking
Drawer mechanism
Very smooth, well damped


Like the previously reviewed Samsung optical drives, this ASUS CRW-5232AS works smoothly and quietly. The maximum noise level at 52X speed was actually 2-3 dBA quieter than with the Samsungs. There was a definite sense of all the mechanical sounds being well-damped somehow. Noise during CD playback or 24X speed operation are modest enough that most users will find it perfectly acceptable.

As for performance, casual use showed no anomalies of any kind, and every CD burn came out perfectly fine. It certainly feels like a fast optical drive. At 174mm, the drive is a bit shorter than most, which is a good thing, as it will help with cable management inside the case. The bundled NERO software is a very popular package, certainly my personal favorite among CD burn software.

The ASUS CRW-5232AS is recommended for noise-aware users.

NOTE: Apparently, an earlier version of this drive did not feature QuieTrack; just make sure you're getting the new QuieTrack version before you buy.

Asus CD-S520/A4

Having reported all the above about the CRW-5232AS, there's really not that much more to say about the CD-ROM version of the same optical drive. It sounds the same during read operations at the same speeds. If you need a quiet read-only CD drive, then the CD-S520/A4 is a good choice. I expect that in this day and age, most users have little interest in read-only optical drives, not when DVD and CD-RW drives cost only marginally more and provide so much more functionality.

We look forward to seeing the Asus QuieTrack technology in DVD drives, which are notable by their absence in the QuieTrack series at this point in time.

Much thanks to Asus Computer for the review samples.
