I bought the OEM version of Sony Optiarc AD-7260S-ZS 24x DVD±RW, it had no booklet & packing but checked the spec from the web & bought it for 1075/-

Bought National dvd dual layer for Rs 25/- & now when I want to write the dvd with nero burning rom the writing speed shows as 4x only :huh:, where as the spec says 24x, why is it so.

Does 24x applicable only for CDs & not for DVDs?

This link says dvd speed to 24x indeed but I get only 2x & 4x speeds could it be that the national dvd are limited to that speed hence it shows only those choices?

Understanding DVD -Recording Speed

Those who use dual layer dvds how much time a dual layer takes to write & verify the data?

UPDATE

Wrote my 1st dual layer dvd having 7.5gb data

DVD writing took 27 mins @ 4x speed (5540 KB/s)

verification of data took another 11mins

Is that speed normal 1 dual layer dvd taking 38 mins to complete data backup?
 
24x max is for single layer dvd. dual layer 4x is acceptable should take 25 mins i guess.write speed also depends on the media used .burn using imgburn and find out all info about your dvd writer and dual layer media.i think 4x burns are fast enough on dual layer media for reliable burns.

The above link shows detailed specs.looks like your burner supports 12x dl dvd burns.unless it is some oem variant with different specs.

USE imgburn to find out more specs.

The problem seems to be with your media,check with imgburn to be sure.

For effective backup to optical media- Media of good quality is of prime importance.Rule of thumb is to burn at half the max burn speed supported by your Media.
i.e. if max supported is 16x burn at 8x.Verify your burn for file consistency.

As for choice of media ,I would recommend verbatim Made in Japan DVD's.they are available at the dealer section of our forum at dvdstoredelhi threads.

Others have got satisfactory results with national dl dvd media on these forums.

Software is more important than hardware these days for optical media.So always use Imgburn!
 
Image burn also shows it as 4x the speed possible with this media. The time taken to write 8gb data is almost the same as with nero burning rom at 27 min + verification time of 11 min.

Changing the sata cable did not make any difference, I believe its the national dvd media speed limit which is at 4x only, though its not mentioned on the dvd. I ten wrote another moser byer dvd which is 16x & that 4.7gb data was done in (write+ verify) 10 mins.
 
MKM001 is 4X capable DVD+R DL. You're not getting more than that out of it, unless you flash a custom FW to the drive that allows overspeeding of that MID.
