Ext USB HDD Vs DVD-RAM disk
I have been using ext. USB HDD for trasfering data between two computers which cannot be connected over network. Now we are thinking of DVD-RAM disks intead of USB HDD. Please let me know your inputs on the following points:
1) A DVD burning SDK will be intergrated to our application to facilitate transfering files to DVD-RAM disk. Is it possible to create a User Interface which is not complex as a CD Burner? Just want a windows Save As dialog to write files into DVD-RAM disk.
2) Is it possible to delete folders selectively from a DVD-RAM or RW disks? Or is it required to erase the whole disk?
I am looking for solution without the usage of packet writing.
3) Is there much difference in the usage of DVD-RW adn DVD-RAM disks?
OS: Windows XP, VC++ 6.0

Re-writes upto 100,1000 times are possible with DVD-RAM disks compared to the 1,000 of DVD-RW.
It has long life.=- data is retained for an estimated 30 years minimum ( I'm not sure how its possible because it uses similar phase change medium as in DVD-RW)
So DVD-RAM looks looks like an ideal media for backup.
It looks like that no DVD burning software required under windows XP. DVD-RAM disks could be used like removable hard disk. Ref: http://en.wikipedia.org/wiki/DVD-RAM

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
I think that NERO does ( nero.com and has a 30 day Eval as well ).
There should be others also.
Not sure how fast this would be vs. a hard drive, Also issues with longevity of the media and the number of rewrites allowed may need to be investigatd.
I hope this helps !
