How Long Does It Take to Burn a Blu-ray Disc?

Blu-ray Burn TimeIn explaining the features and benefits of recordable Blu-ray discs, many comparisons are made to standard CD and DVD recordable discs. While there are many similarities between these optical media formats, they are not the same. One great way to illustrate the advantages of Blu-ray is to use existing CD and DVD technologies as a yardstick to measure differences.

We know that a CD-R disc holds 700 megabytes of information. A recordable DVD holds 4.7 gigabytes, which is about 6 times more storage space than a CD. In comparison, a recordable Blu-ray disc holds a whopping 25GB of storage space! This is equivalent to 5.8 DVDs of information, or 36 CDs. Storing that much information on a disc that costs about $2 dollars each is simply mind-boggling.

Another way in which blank Blu-ray discs excel is their maximum write speed. As we have discussed in a previous article about burn speeds, the rates at which CD, DVD, and Blu-ray discs are burned are entirely different from each other. Recording a CD at 1X is not the same as recording a DVD at 1X. The same is true for Blu-ray, where 1X is equivalent to approximately 2.4X for DVD.

Many people want to know: how long does it take to burn a Blu-ray disc? Again, we turn to CD and DVD media for a quick comparison. Recording a full 700MB CD-R disc takes approximately 2 minutes at a maximum speed of 52X. Recording a full DVD disc takes about 4 to 5 minutes at a maximum write speed of 20 to 24X.

For Blu-ray, recording a full 25GB disc takes about 16 to 32 minutes at 4X – 6X. While this may seem slower than CD and DVD by comparison, it’s actually faster. This is because Blu-ray drives have a higher data rate than CD or DVD drives. Although their write speed is in fact MUCH higher, the process takes several extra minutes because of the massive quantitiy of data that must be written to the disc.

Most Blu-ray drives, such as the ones found in the Accutower Blu-ray duplicator towers, feature high-speed recording for maximum performance. For more information about recordable Blu-ray discs, please visit us at CDROM2GO.com today!
