Why each option
Blu-Ray discs offer significantly more storage capacity compared to CD-R and DVD formats, making them suitable for high-definition media and large data backups.
DDR (Double Data Rate) refers to a type of RAM (Random Access Memory), which is volatile memory used for active data processing, not persistent storage capacity like optical discs.
A CD-R (Compact Disc-Recordable) typically stores 700 MB of data, which is much less than a DVD or Blu-Ray.
A standard single-layer Blu-Ray disc can store 25 GB of data, while dual-layer discs can store 50 GB, which is considerably larger than the capacities of CDs and DVDs. Blu-Ray technology uses a blue-violet laser allowing for smaller pits and therefore higher data density.
A standard single-layer DVD (Digital Versatile Disc) typically stores 4.7 GB of data, which is less than a Blu-Ray disc.
