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.
