A Short Word About The DVD

The DVD, also known as the "digital Versatile Disc" or "Digital Video Disc" is an optical media storage device. The DVD is primarily used to store videos in high quality, but it can also be used to store data or pictures. The DVD is the same size and shape as its predecessor the Compact Disc, but can store up to six times as much information.

There are many types of DVD, and their functions can vary widely. For example, DVD-ROM (Read Only Memory), has data that can only be read and not written, DVD-R and DVD+R can record data only once and then function as a DVD-ROM. DVD-RW, DVD+RW and DVD-RAM can both record and erase data multiple times.

DVD's of different types also have different write speeds, as can be seen below.
Single Layer(4.7GB) write speeds
1x (CLV) = about 58 minutes
2x (CLV) = about 29 minutes
2.4x (CLV) = about 24 minutes
4x (CLV) = about 14.5 minutes
6x (CLV/ZCLV) = about 10-12 minutes
8x (PCAV/ZCLV) = about 8-10 minutes
12x (PCAV/ZCLV) = about 6.5-7.5 minutes
16x (CAV/ZCLV) = about 6-7 minutes
Dual/Double Layer(8.5GB) write speeds
1x CLV = about 105 minutes
2.4x CLV = about 44 minutes
4x CLV = about 27 minutes
Single Layer (4.7GB) read speeds
1x read speed is 1.321MB/s = ~56 minutes
6x CAV (avg. ~4x) read speed is max 7.93MB/s = ~14 minutes
8x CAV (avg. ~6x) read speed is max 10.57MB/s = ~10 minutes
12x CAV (avg. ~8x) read speed is max 15.85MB/s = ~7 minutes
16x CAV (avg. ~12x) read speed is max 21.13MB/s = ~5 minutes

As the advancement of High Definition technology becomes more widespread, the DVD will slowly be replaced by the more advanced Blu-Ray and HD-DVD discs.
