The ASUS CRW-5224A-U is an External CD-RW drive with 52x Write, 24x
ReWrite and 52x Read capabilities. The drive complies with the Universal
Serial Bus 2.0 (USB 2.0) specifications and comes equipped with the
latest innovative technologies in CD recording.
ASUS External CD-RW drives are accentuated by the latest innovations in
CD-recording technology, namely: FlextraSpeed
(Double Dynamic Suspension System II) and the Constant Angular
Velocity (CAV) recording method.
The following sub-sections describe these technologies in detail.
The ASUS FlextraSpeed™ technology provides the optimum solution to
ensure quality recording when using discs that require flexible speeds. The
CRW-5224A-U drive employs this technology that allows automatic
recording speed adjustment based on the recording media.
In addition to the fact that there are low and high quality recording media,
various other factors such as dye layer, temperature, humidity, dust,
fingerprints, etc., affect the recording characteristics of CD-R and CD-RW
discs. Due to these factors, some discs may not be able to stand the high-
speed capabilities of the latest CD-RW drives. The FlextraSpeed™
technology solves this problem by automatic assessment of the disc
quality and recording capability. The recording speed is based on these
factors. If you use a high quality recording disc, you can maximize the
recording capability of the drive and get the best quality output. If you use
a low quality disc, the drive speed adjusts to the level that is most
appropriate for the disc, still optimizing the disc recording capability.
The FlextraSpeed™ technology also helps maintain the CD-RW drive
because of the controlled motor rotation speeds and reduced noise
caused by spindle air, thus prolonging the drive motor's life and ensuring
