Having just bought a decent DVD-RW drive, I’m trying to work out why I never bought one before.  It’s dumping 4 gig of data quite quickly, starting around 11 MB/s, and topping out around 22 MB/s.  8 GB of 70 archived so far, so 8 more disks to go.  I’ll have to generate a TOC type CD or something to go with the archive – perhaps a 64 MB USB stick will work (got one lying around somewhere), just detailing which disk has which files.
