Read this for a more detailed explanation on what is going on. This pertains to both internal and external drives.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 minutesDual/Double Layer(8.5GB) write speeds
1x CLV = about 105 minutes
2.4x CLV = about 44 minutes
4x CLV = about 27 minutesSingle Layer (4.7GB) read speeds
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 minutesDVD Write types
CAV = Constant Angular Velocity, the DVD is written at a constantly increasing speed.
CLV = Constant Linear Velocity, the DVD is written at a constant speed.ZCLV = Zone Constant Linear Velocity, the DVD is divided into zones. After each zone the write speed is increased.
PCAV = Partial Constant Angular Velocity, the DVD is being written at an increasing speed until a certain speed. After this speed it will not increase anymore.
