ϼ™.4 or 4.7 GB DVD RAM , music storage

vbimport

#1

I am using a LG GSA-4082B writer on a windows XP

  1. in terms of reliability of storing data flawlessly, does it make any difference if I store it on a 4.7 GB or 9.4 Gb RAM ( price is not an issue )

  2. Is it correct to say that DVD RAM is the best media to store music ; even better than those special disks(CDR) meant to store music

  3. I have so far burnt 50 DVD RAMs on my writer ; is there any way I can tell if there is wear and tear , or what should I do to maintain the writing quality

  4. what is the problem of oveburning a DVD R /RW , ( i think the max is 4.6 GB on a nero ? )

Hi :slight_smile:

  1. In short: no.

  2. I don’t think so. CDR for “storing music” may be problematic if you create AUDIO CDs out of your files, because CD-Audio doesn’t have a good error correction system. If you store your .wav files, they’ll be fine on data CDRs as long as you use premium, stable CD discs (like Verbatim) and you burn them correctly.

  3. As of now there is no way (yet) for us, end-users, to check the burning quality of RAM media (that I know of). But it seems like it’s not an issue as most DVD-RAM are quite reliable.

  4. Risk of data loss because the edge of the writing area is the most prone to problems. Personally, I think that overburning optical media is just a sport and should be avoided in all cases where data is important.

Looks like DVD RAM is the best media to store music in terms of lesser prone to errors and hopefully better music quality ; and this is better when compared to those special disks(CDR) meant to store music

I use 9.5gb ram discs to store my music. Be aware that the discs are Double sided, so unlike a dual layer dvd, 4.7 gb is stored on either side, so you have to flip the disc over. This doesnt really bother me.

    2)have you lost any data on a 9.5 GB ; as compared to a 4.7 GB DVD RAM

Nonsense. “Music quality” or “audio quality” has 100% nothing to do with the media used for storing audio files. It’s totally independant. As long as you are handling audio [I]files[/I], the media makes no difference at all in audio quality. HD, CD, DVD, you name it.

and this is better when compared to those special disks(CDR) meant to store music
I think you’re mixing things up. “Special CDRs for music” are for burning AUDIO CDs, that you can play in audio CD players.
If you burn the audio FILES (.wav, .mp3…) by creating a DATA CD, there is no difference at all between these and “regular” CDRs.

well the technology used on dvd ram supposedly assures you dont lose any data because the disc technology verifies the data as it’s being written. I havent been using it that long and have only been using it for archive purposes so have tested that all the data is 100% ok, but I believe that it is. Handle dvd-ram by the edges and never touch the disc/centre and I think it will fine. Thats what I do at least.


#8

I can’t imagine a more inappropriate use for RAM discs than “storage”. RAM is intended for use as a drag-n-drop type mode of transporting and short term backup, etc. CDR is more than adequate for audio storage, assuming it’s quality media and well-burned. The only conceivable reason to use RAM for this is if you frequently erase or update the files on the disc.

  1. 9.4 GB DVD-RAM is Double sided and has to be flipped to be used so the chance of the data side getting scratched is bigger than on the 4.7GB disc so it has to be handled more carefully. Beside of this there is no difference concerning quality what so ever.
  2. DVD-RAM is in my opinion the best format of all DVD formats for backingup data. RAM does verify the data while writing to it and has as far as I know a very good error correction.
  3. There seem to be drives capable of doing quality scans on DVD-RAM. Well at least YSS uses a LITE-ON DVDRW SHM-165P6S MS0N to check DVD-RAMs (http://homepage2.nifty.com/yss/sw9587/sw9587_ram.htm) .
  4. Risk of Data being lost

#10

I agree with koba on 3). I think the Lite-On SHM-165P6S is about the only drive right now that does quality scans and supports DVD-RAM. Samsung may have a drive with similar features, but a)Samsungs are not really trusted as reliable scanning drives and b)they are not that easy to get hold of as that model of Lite-On.


#11

In one respect, you are right. I’d have to have to transfer 4.7gb in one go at 3x or whatever. But as a backup medium its good. I only have 2, so instead of writing on a cd and thinking ok i;ll store it in a jewel case and hope it doesnt get lost amongst my 100’s of other jewel cases, I can clearly see which are my valuble ram discs. But thats just me of course.

I think you’re mixing things up. “Special CDRs for music” are for burning AUDIO CDs, that you can play in audio CD players.
If you burn the audio FILES (.wav, .mp3…) by creating a DATA CD, there is no difference at all between these and “regular” CDRs.

Actually I think you’re wrong. While I don’t know what the original poster meant by special audio CDRs I suspect the poster meant “Consumer Audio”/SCMS CDRs (I didn’t actually know they still exist). While these discs may work better then average CDRs in CD players, CDRs have a variety of success rates in audio CD players depending on brand and type (reflective layer and dye). My experience is that compatibility nowadays especially is good with few problems.

However as I’ve said, the primary purpose of consumer audio CDRs is not to do with their compatibility with audio CD players nor their longetivity for that matter. They can be used with consumer level stand alone audio CD recorders. Consumer level stand alone audio CD recorders never really caught on but the idea was everyone who was burning audio was effectively pirating, (even if this is a silly assumption) so the manufacturer pays a fee to the recording industry for each disc and in exchange, they produce these special discs which consumer level stand alone audio recorders can use. These devices are not allowed to use normal CDRs.

Since they are intended for stand alone recorders, they tended to be optimised for low speed recording but I don’t know if this is still the case.

Also, as others have said, if you’re storing audio for archival purposes, DO NOT BURN THEM AS AUDIO CDs. Store them as wav files or whatever on a data CD (preferbly mode 1 IMHO, in theory mode 1 or mode 2 form 1 shouldn’t matter but my experience is mode 2 form 1 can be more problematic with some software and drivers when it comes to recovery). For even greater chance of data recovery, you might want to include some parity (PAR2) files but this won’t help you if the directory tree or whatever becomes damaged and the disc becomes unrecognisable.

Although I agree, when it comes to consumer level optical media, DVD-RAM appears to be your best bet at the moment

What’s wrong with burning several DVDRs of the same backup, on different MIDs for safety? Costs less than one SL DVD-RAM, and several backups are safer than a single one, even more so if you store them in different places (friends, family etc…). The same can be done with CDRs.


#14

What part? :confused: - I’m not sure what’s the disagreement here…


#15

From what I can tell, you’re saying that these CDs are designed to be used for audio CDs so they work well with audio CD players

I think you’re mixing things up. “Special CDRs for music” are for burning AUDIO CDs, that you can play in audio CD players.

I’m saying there is little or no design intention for audio CD player compatibility. They are designed to be used with consumer audio CD recorders and more importantly, the royalty fee is paid. Or to put it a different way, the primary difference between these special audio CDRs and normal CDRs is that the royalty fee is paid and the have the special mark and can therefore be used with consumer audio CD recorders.


#16

I just like the idea of being 100% sure that what ive written is more fail proof than a regular dvd for one, and the other is that I take care of my dvd ram discs a HELL of a lot better than my regular dvds. It also helps that you have to store them in their own jewel case every time you want to add more data lol :slight_smile:


#17

Well, I use DVD-RAM for backups of stuff from my HDD that hasn’t made it to +R yet, and two sets of +R (as mentioned, different brands, or at least different MIDs). :slight_smile:

[/quote]
Media explicitly described as “Audio CD-R” are designed to be used in standalone HiFi-Recorders. There is a special mark on these media, the recorders verify if that exists, else they refuse recording.
In addition, the higher price includes an additional fee for the starvin music industry :wink:

question … How to do all that ; what media do you use ?
2) what is MID ?

can I confirm my understanding that instead of buying a 2.5 inch/ ? inch Hard disk (200G) ; is better to own 45 DVD RAM disks (45* 4 .5 = 200) ;

  1. As compared to DVD RAM, Hard disk are more prone to loss of data/errors should you drop the hard disk ; carry the hard disks in temperature of 45 degree celsius etc

  2. by owning DVD RAM , we are spreading that data loss risk by spreading that towards many DVD RAM s( 4.7 GB ) instead of concentrating all the 200 Gb data in one Box .
