DVD-RW Discs – Rewritable, Reliable Storage at the Best Price
DVD-RW Discs remain one of the most versatile and affordable ways to back up files, record videos, and store important data offline. Each disc can hold up to 4.7 GB of information and be rewritten hundreds of times without losing quality, making DVD-RW a dependable choice for home users, educators, and small businesses that still value physical media.
Introduced as an evolution of standard DVD-R discs, the DVD-RW format uses phase-change technology that allows data to be erased and rewritten. It’s the ideal solution for recurring backups, testing, and projects that need flexibility before committing to permanent storage.
Why Choose DVD-RW Discs?
- Rewritable Design: Erase and reuse each disc up to 1,000 times.
- Reliable Storage: Maintains stable performance and readability for years.
- Low Cost: Store data for pennies per gigabyte.
- Universal Compatibility: Works in most DVD burners and players.
- Offline Security: Immune to power failures and online threats.
DVD-RW Specifications
| Format | Capacity | Rewritable? | Speed | Common Use |
|---|---|---|---|---|
| DVD-RW SL | 4.7 GB | Yes | 1x – 6x | General data and video storage |
| DVD-RW DL | 8.5 GB | Yes | Up to 8x | Extended backups and media projects |

DVD-RW vs BD-RE and CD-RW
DVD-RW offers the perfect middle ground between BD-RE Blu-ray and CD-RW formats. It’s cheaper than Blu-ray but holds far more than a CD, making it ideal for lightweight archival or frequent rewrites.
| Format | Capacity | Rewritable? | Speed (MB/s) | Best For |
|---|---|---|---|---|
| BD-RE | 25–100 GB | Yes | 72 | High-capacity professional backups |
| DVD-RW | 4.7–8.5 GB | Yes | 11 | General use, test projects, home video |
| CD-RW | 700 MB | Yes | 3.6 | Audio and small file storage |
