Discussion Overview

The discussion centers on comparing the speed of 16x DVDROM drives with 56x CDROM drives, exploring the implications of these ratings on performance and usage. Participants examine the relevance of these speeds in practical applications, including DVD playback and data transfer rates.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant questions which is faster between a 16x DVDROM and a 52x CDROM, noting the differences in their speed ratings.
  • Another participant suggests that the need for higher-speed DVD players is questionable, citing their own experience with a 4x player that performs adequately for movie playback.
  • A participant explains that the 16x rating for DVDs refers to data transfer speeds that differ significantly from those of CDs, with 1x for CDs being 0.15 MB/s and 1x for DVDs being 1.35 MB/s.
  • Further discussion includes the idea that as DVDs may be used for various purposes beyond movies, the demand for faster DVD drives could increase in the future.
  • One participant acknowledges the oversight of data storage considerations in the original comparison.
  • A participant mentions the cost of DVD players in Malaysia, highlighting the availability of multifunctional devices that can play various formats.

Areas of Agreement / Disagreement

Participants express differing views on the necessity and practicality of higher-speed DVD players, with no consensus on the implications of speed ratings for different uses. The discussion remains unresolved regarding the overall superiority of one format over the other.

Contextual Notes

Participants do not fully explore the implications of data transfer rates in practical scenarios, and there is a lack of clarity regarding the specific contexts in which speed ratings apply.

CD ROM is up to 56X (Aopen),
but DVDROM is only 16X,
which one is faster? 16xDVDROM or 52xCDROM ?

Why DVDROM is not rated at 52X ?

Are you talking about DVD burners or just the players? I don't know why anyone would want a 16x or above dvd player. I have a 4x player in my computer and I can play any dvd movie flawlessly. There just isn't a need.
 
The "16x DVD" means the drive can transfer data 16x faster than a normal for a dvd disk (movie). This doesn't say ANYTHING about CD performance. And since they transfer different things, 1x for a cd rom is .15 megabytes/second whereas 1x for a dvd is 1.35 mb/s

http://www.plextor.com/english/products/pdfs/20_10.pdf is a link to a cd-rw/dvd combo drive. It writes cd's at 20x, rewrites cd's at 10x, reads dvd's at 12x and reads cd's at 40x.

Very good point.
As long as the data transfer per second is more than the size of data of the frames of that second, then the DVD is playing flawlessly.
But ... suppose some day the DVDs are used for other purposes (and they actually are), then it will no more be a matter of number of frames, you will (then) appreciate a faster DVD drive.

Your site STAii, I didn't take data storage into consideration.
 
in Malaysia,
a DVD player that can play DVD,MP3 from CD, CCDR, SVCD etc.,
just cost about 120USD for a branded one (JVC, philips).
