DVD-R DS (DS stand for Double Side) is also called DVD-10 (Dual Side, Single Layer) or DVD-18 (Dual Side, Dual Layer), it is a sub category of DVD-R. A DVD-R DS has a storage capacity of 8.75 GB (DVD-10) or 15.9 GB (DVD-18).
DVD±R/W (also written as, DVD±R/RW, DVD±R/±RW, DVD+/-RW, DVD±R(W) and other arbitrary ways) handles all common writable disc types, but not DVD-RAM. [1] A drive that supports writing to all these disc types including DVD-RAM (but not necessarily including cartridges or 8cm diameter discs) is referred to as a "Multi" recorder.
DVD-R DL (DL stands for Dual Layer [1]), also called DVD-R9, is a derivative of the DVD-R format standard. DVD-R DL discs hold 8.5 GB by utilizing two recordable dye layers, each capable of storing a little less than the 4.7 gigabyte (GB) of a single layer disc, almost doubling the total disc capacity.

As of July 2008, over 95% of Blu-ray movies/games are published on 50 GB dual layer discs with the remainder on 25 GB discs. [10] 85% of HD DVD movies are published on 30 GB dual layer discs, with the remainder on 15 GB discs. [11] [12] The choice of video compression technology (codec) complicates any comparison of the formats.
DVD+R DL discs employ two recordable dye layers, each capable of storing nearly the 4.7 GB capacity of a single-layer disc, almost doubling the total disc capacity to 8.5 GB. Discs can be read in many DVD devices (older units are less compatible) and can only be created using DVD+R DL and Super Multi drives.
The additional capacity comes at a cost: DVD±DLs have slower write speeds as compared to DVD±R. [64] DVD-R DL was developed for the DVD Forum by Pioneer Corporation; DVD+R DL was developed for the DVD+RW Alliance by Mitsubishi Kagaku Media (MKM) and Philips. [65]
The DVD and Blu-ray discs hold a higher capacity of data, so reading or writing those discs in the same 74-minute time-frame requires a higher data transfer rate. Drive speed can be limited intentionally to reduce noise from the drive or slow down ripping, such as the firmware component Riplock.
114 minutes of uncompressed CD-quality audio at 1.4 Mbit/s is approximately 1 GB. A single-layer DVD+R disc can hold about 4.7 GB. A dual-layered DVD+R disc can hold about 8.5 GB. A single-layer Blu-ray can hold about 25 GB. The largest Nintendo Switch cartridge available on the market holds about 32 GB. A dual-layered Blu-ray can hold about 50 GB.
