Anyone thought about DVD-Ram? I've been thinking about them for backups
recently and they look quite attractive. A DVD drive, which you can use for
all the other CD and DVD formats is £599 in a mag here and a 5.2Gb DVD-Ram
is only £26.85.

Possibly a little pricey compared to the lower end tape solutions and not
the storage capacity of the higher end DLT but as an in-the-middle solution
it looks quite attractive at that price.

Seems like it would blow a Jazz disk out of the market and given some time
to mature it might start threatening the lower end super-floppy type
devices. CDROM drive prices have certainly plummeted since they came out, if
DVD technology does the same this is going to look like a very attractive
device.

I don't know how one of these DVD-Ram media would stack up against tape when
it comes to longer term storage but I suspect very well. In terms of
performance I suspect it's much better than tape.

As you can probably see, I've not looked into this much, DVD-Ram just
recently caught my attention and the price/Mb of the media really surprised
me.

Paul.
