These TDK Systems DVD-RW discs work well for me. Some users have said that these say DVD-RW on them but are really DVD+RW, which won't write and/or read in some DVD burners or DVD players. I guess I lucked out bcause these work fine in my DVD burner, DVD ROM drive, and my standalone DVD player. So, keep ths in mind when buying these. If they don't work, return them because they're probably mislabeled.
Most current DVD-RW media write at slower 1x-4x speeds, so these 4x speeds are par for the course. Burning a full disc can take about 15-20 minutes.
What it lack in burning speed, it makes up with its being ability to be rewritten many times.
These are perfect for computer backups when your computer needs to be reformatted or transferring big chunks of data to another computer. It's also great for movies that you only want to watch once. The possibilities are endless.
DVD-RW media is perfect when you have data that you don't want to store permanently. TDK is a medium quality brand of discs that aren't for everyone but they work for me.
I usually buy these in spindles of 25 because I don't need to use them often and be rewriteable, I can use one disc several times.
