Now let's have a look at how the drive performs with DVD media. This time, a set of SL and DL DVD media was used. The drive is capable of reading at 12X maximum speed for single layer DVD ROM and at 8X for dual layer DVD ROM media.

DVD-ROM SL media -

Drive	Average Speed	Full Access Time
LiteOn DX-401S BD-ROM	9.12X	221 ms
LiteOn DH-401S BD-ROM	9.10X	197 ms
Pioneer BD-ROM BDC-202	9.42X	331 ms

PTP DVD-ROM -

The two layers of a PTP DVD-ROM disc are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer, progressing towards its outer range.

A small drop in the reading speed of the second layer of the disc was reported at around the 7.75GB mark.

OTP DVD-ROM -

The first layer of an OTP dual layer DVD-ROM is read exactly the same way as the first layer of the PTP disc we tested previously. The difference here is the reading strategy of the second layer of the disc. The beginning of the second layer is located in the outer part of the disc, so the drive starts reading from the outer tracks and progresses towards the inner part of the disc.
