Hi, I want to buy some rewriteable Media:

I have the following drive: (product: _NEC DVD+/-RW ND-6650A)

Write Speed: DVD+R: 16x max., DVD+RW: 8x max., DVD+R DL: 4x max., DVD-R: 16x max., DVD-RW: 6x max., CD-R: 48x max., CD-RW: 24x max.

a) Which format is better for data security? Assume the disc get damaged? I want to use these discs for backups.
b) Which one burns faster? My drive is able to burn DVD+RW 8x and DVD-RW 6x. There are now media available with these speeds!
c) Which one to buy (amazon.de; no shipping costs )?
*) Ricoh DVD+RW 8x Speed, 10 pieces, Pack Slim Jewel Case DVD-Rohlinge: 14,99
I trust Verbatim, Ricoh is for me noname(sorry for saying that, but i don*t know this brand).
There are Verbatim +RW discs with a similar price and specification.
*) Verbatim DVD-RW 4,7GB 6x Speed, 5pieces Pack Jewel Case DVD-Rohlinge : 10,99
*) Verbatim DVD-RW 4x Speed, 10 pieces; Pack Jewel Case Scratch Resistant Surface DVD-Rohlinge : 14,99
d) Whats the difference between the formats DVD+RW and DVD-RW? I have used google a lot for a week now and don*T know the answer jet!

Apparently +RW have more error correction than -RW so should be better for long-term reliability.

b) Which one burns faster? My drive is able to burn DVD+RW 8x and DVD-RW 6x. There are now media available with these speeds!
If you're after reliability then you're better recording at 1x. Otherwise, obviously, the answer is +RW.

c) Which one to buy (amazon.de)?
*) Ricoh DVD+RW 8x Speed, 10 pieces, Pack Slim Jewel Case DVD-Rohlinge: 14,99
*) Verbatim DVD-RW 4,7GB 6x Speed, 5pieces Pack Jewel Case DVD-Rohlinge : 10,99
Personally I wouldn't go for either of these - you should be able to get them far cheaper from specialist media suppliers. Otherwise it depends on whether you're going with +RW or -RW.

d) Whats the difference between the formats DVD+RW and DVD-RW? I have used google a lot for a week now and don*T know the answer jet![/quote]
The main difference is that +RW supports random access (like a hard drive) whereas -RW supports only sequential access (so you have to either append data or wipe and rewrite everything). Beyond that you're getting into technical details - see http://www.cdfreaks.com/reviews/Why-DVDRW-is-superior-to-DVD-RW for some of these.

thank you,

I have seen DVD+RW is newer then DVD-RW (Philips). It seems DVD+RW have lossless linking of multisession-DVDs. Also DVD+RW have higher speeds, then DVD-RW currently available.

So I will go for the DVD+RW discs. DVD+RW-DL discs seems to be not technical possible, so I don*t wait for them :roll:

.

Ill buy them tommorow at amazon.de, no shipping cost at 20, So I buy a book and this package one time.
