Because my previous DVD Writer drive was not so good and would get errors on burning and reading, I could basically use it to distinguish high-quality DVDs from low-quality ones. HP's 16X DVD+R is definitely high quality. This media is reliable, and I rarely get any errors, if any at all. Compared to other brands of DVD media, this is probably one of the best, along with TDK brand media. Even those data DVDs I've burned years ago can still be copied without any errors.
The price is also relatively cheap, for its high quality.
Even with my new, more reliable DVD drive, I continue to use HP 16X DVDs, and will continue to use it for years to come.
I recommend using this media to store your important data, if you want to be able to still use them in the future.
