The difference between 'plus' and 'minus' DVD writers comes down to features. Despite some headway being made by the companies pushing DVD-RW, DVD+RW is still a more flexible format for those interested in creating movies and storing data. The ability to update individual files on a +RW means you can edit movies straight off the disc, which can save a significant amount of time if you're only making minor changes.

On the other hand, +R/RW discs are less likely to work in older DVD-ROM drives and component DVD players. While we've never had any problems ourselves, it's something prospective buyers need to consider carefully before deciding on a format.

The A1 offers slightly above-average performance for its speed; despite being 'rated' at the same level, most DVD+RW drives can differ by as much as 90 seconds in their writing speeds. At 2.4x, the A1 burnt our 4.32GB test image to DVD+RW in 22 minutes 31 seconds, which is slightly above average. On the other hand, it took 24 minutes 53 seconds to burn a standard +R at the same speed, which is a little above average.

Something the Mitsubishi drive has going for it is price – it's cheaper than the other DVD writers we reviewed this month, which makes it a far more palatable option. Couple this with the fact it can write faster than either of the aforementioned drives, even if it's only by four minutes per disc at most, and the deal sounds just that more sweeter.

Although there are faster +RW drives available, most of them are significantly more expensive than Diamond's A1. If you're looking for a DVD+RW on the cheap, this one makes a fine choice.
