As well as 'cold storage' archives, it would be interesting to see how suitable these disks are for a home computer's 'video library' -- which would generally consist of large sequential files, which would generally be created and deleted as a single unit, but whose timeframes may be more likely to be months (movies) or days (this week's television programmes) rather than a true cold storage scenario.
This would also make the size of the rewriting 'bands' a matter of interest. If relatively small (64-100MB) this should not adversely affect the drive's usage for this purpose, if significantly larger (e.g. 1GB), it might (moving the driver closer to purist Write-Once-Read-Many in its utilisation).
I look forward to reading the review.
