DVD-RAM is a rewritable format supported by the DVD Forum. A DVD-RAM can be seen as a removable hard drive. However, as any other hard drive the DVD-RAM must be "prepared" (formatted) before the first use. A DVD-RAM disc must be formatted using the UDF (Universal Disk Format). Usually, a 4.7GB DVD-RAM should be formatted using the UDF 1.5 or the UDF 2.0 format.

Notice that in the above tests we showcase the maximum recording speeds supported by the drive with the specific DVD-RAM media. In case you are using your DVD-RAM discs as a removable hard drive through your Windows OS, you may experience slower burning. That because the DVD-RAM format features an automatic verification technology that results to safer but slower recordings.
