New DVD Burners To Double Capacity
clester writes "CNN reports that new dual-layer DVD-burning drives will be released very soon by Philips and Sony that will double the capacity of DVD drives, making a complete copy of your dual-layer DVDs theoretically possible. It will use dual layer technology that will hold up to 8.5GB, and will cost around $230 for an internal and $330 for external, burning all 8.5GB in approximately 45 minutes."
But will the new dual layer DVD's be compatible with set-top boxes or legacy DVD ROM drives???
double sided dual layed dvd's... possible ?
Isn't that slow? The Pioneer DVR-106 I'm currently using does a full 4.5GB in less than 20min at 4x, and the 107 at 8x does it in about 10min. 45min is almost 5 times longer for only double the capacity. That's somewhat disappointing.
OTOH I suspect it could burn regular single-layers DVDs at a better speed. Might be worth it for those who need a lot of them or can wait, but it won't be for me at first. Unless there's an error in that number...

You'll tell me that in 10 years when 50% of your disks will be as good as dead.
Seriously, the quality-longevity of the media is a great concern for some people that wants to use it as back-ups. Any numbers over there anyone?
Write boring code, not shiny code!
I say that because I had always been told that dual layer DVD's were "sandwiched" together after each layer had been burned separately. This obviously means a single disc burned all at once with dual layers. So what's the deal?

They will be marketed only for Windows PCs, but the external one should work on Macintosh computers with the proper third-party software. correct me if i'm wrong, but aren't ide devices pretty platform independent? why wouldn't an ide device for win32 work in ppc? and, (what i actually care about) are they going to work in some sort of proprietary bs that will prevent me from using it in linux?
Still the same old problem - not enough to back up a 400 Gb drive, and how reliable are these new DVDs for long term storage??
Tbe new DVD may offer more capacity for redundancy though - you can write multiple copies of a large folder to the same disk with a lot of space left over so any degradation is unlikely to blow away all your data at once.
Know your pads. One time pad: good for cryptography. Two timing pad: where to take your mistress.
Why would Apple switch away from Pioneer, who has already demonstrated that their current drives can do dual-layer burning, with only an updated firmware. (translated link to actual article is here)

A single data-point does not an argument make. Hi-Speed USB 2.0 does have a higher raw transfer rate than FireWire 400, but USB in general has worse latency, and higher CPU utilization, than FireWire.
I'm skeptical of the source of this data, also... since it's CNet. I wonder what testing methodology they used? (It's possible the "statistics" about transfer rates may have been influenced by anti-Apple sentiments festering at CNet.)
still 4G of data is a lot and I don't like hanging them with a thin rope. So after awhile I par all the files to create a 10%~20% backup. Backup the backup. I am curious if anyone else does this.
Not so much backup the backup, but instead I create PAR2 files and put them in the VIDEO_TS folder (in the case of video DVDs), or put everything in ZIP files in the root folder and then create a PAR2 set (using QuickPar) for them.
For data, I usually shoot for 10-15% recovery data on the disk (maybe more).
For video, 1-3% is plenty. So far I've not had any problems leaving the PAR2 files in the VIDEO_TS folder. When the disc starts to show errors, I have the option of using ISO Buster and the PAR2 recovery data to restore the corrupted data prior to burning it to new media.
Still not as secure as a second physical copy, but beats finding out a disc is going bad and not being able to do anything about it.
