VERITAS RecordNow

We used VERITAS RecordNow program to copy a DVD-movie to three rewritable media: TDK DVD-RW 4.7GB, Fujifilm DVD+RW 4.7GB and Verbatim DVD+RW 4.7GB certified for 2.4x. The DVD-RW disk required most time to accommodate the DVD image: 57 minutes 4 seconds. DVD+RW disks were faster: we burned the Fujifilm in 22 minutes 35 sec and the Verbatim – in 23 minutes 9 seconds. The difference is striking. Even accounting for a higher nominal burn speed of DVD+RW media, it seems like Sony DRU500A favors them more.

VERITAS Simple Backup

Disk type	Format time, sec	Write time during disk copy, min:sec
DVD-RW TDK	32	44:57
DVD+RW Verbatim	41	16:51
DVD+RW Fujifilm	39	18:33

Here, we used the backup utility to copy a few folders (total weight equaled 4.493GB) from the hard disk to the three media mentioned in the previous test. Before the actual data transfer, the utility took some time to format the disks. As the table above shows, DVD-RW required less time for this preparation step. As for the backup itself, this medium proved to be the worst choice, again. DVD+RWs were burned twice as fast.
