How is DVD better than CD?
A Digital Versatile Disc or Digital Video Disc (DVD) is similar to a CD-ROM in that you can only read data from it. The main difference is that the DVD can store much more data than a CD-ROM, CD-R, or CD-RW. A DVD+R can only record data once, then the data becomes permanent on the disc.
Can a DVD hold more than 4.7 GB?
DVDs come in two sizes: 4.7GB single-layer discs and 8.5GB double-layer discs. Windows supports burning DVDs in both the 4.7GB and 8.5GB size, so if you need to burn some larger personal files or an ISO image file larger than 4.7GB, use an 8.5GB double-layer DVD.

Can a hard drive last 10 years?
—is that the average hard disk lasts somewhere between 3 and 5 years before it will fail and need to be replaced. Some will last beyond 10 years, but these are the outliers. When an HDD fails, it will not be repairable without great expense, and so the data stored upon it will very likely be lost forever.
