Internal DVD R/RW Burner

Durability of DVDs is measured by how long the data may be read from the disc, assuming compatible devices exist that can read it: that is, how long the disc can be stored until data is lost. Five factors affect durability: sealing method, reflective layer, organic dye makeup, where it was manufactured, and storage practices. According to the Optical Storage Technology Association (OSTA), "manufacturers claim life spans ranging from 30 to 100 years for DVD, DVD-R and DVD+R discs and up to 30 years for DVD-RW, DVD+RW and DVD-RAM".

With the cost of internal DVD recorders ranging from around $20 to under $100 this makes for a very inexpensive backup system. The main hold back of this type of data backup is the requirement of a hands on backup, or the purchase of a quality backup software to enable automated backups after a fresh DVD has been placed in the burner.
