Even if DVD+RW is "superior" to DVD-R. What does it REALLY buy you? Is there any REAL practical use for writing to the 4GB position on a virgin media? And personally i would NEVER use a rewritable medium that isn't build into a caddy. (Neither - or + fit this requirement. DVD-RAM would fit) As i "joke" i bought 2 DVD-RW media and used them to transport some data to a college of me, after 3 rounds the media weren't usable anymore, because of to many scratches. So the R(e)W(rite) is more theoretical then practical in my eyes. (OK there are "DVD+R" now) If i need TRUE "random" access, DVD-RAM is much better for the job. OK disadvantage is that nearly nobody has this (if you want to use such a media to transport data.) and even if DVD-RAMs were readable by a normal DVD drive the media wouldn't fit because i haven't see a DVD drive with a caddy latly. For transporting data to/from the place i work i use a 20GB 2,5" HDD build into a firewire-enclosure. With around 15MB/s this outperforms everything else on the portable market. (Excluding 3,5 HDD built into a firewire enclosure) Bis denn -- Real Programmers consider "what you see is what you get" to be just as bad a concept in Text Editors as it is in women.
