DVD reading tests

- Single Layer DVD-ROM (Click for CDSpeed results)

Again, as was the case with CD media, the BTC drive's reading speed is very close to that of the other two drives.

The seek times are very good.

- Dual Layer PTP DVD-ROM (Click for CDSpeed results)

The two layers of a PTP DVD-ROM disc are read sequentially with the drive starting the read process from the inner tracks on the disc, which is the beginning of each layer, and progressing outwards towards to the outer tracks for each layer.

The DVD dual layer speed results reach a high level.

The seek times continue to impress.

- Dual Layer 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 disc's second layer. The beginning of the second layer is located in the outer part of the disc, so the drive starts reading from the outer tracks inwards towards the inner tracks of the disc.

As can been seen from the following screenshot, the OTP dual layer DVD test disc had the same speed as the PTP. The seek times are at about the same levels.

- DVD Ripping Tests

We measured the DVD-Video ripping speed of the BTC drive using the latest version of DVD Decrypter. The DVD Video title is the "Matrix" pressed DVD-Video.

Here, the BTC drive was the fastest. The reported 8872 kb/s is a good transfer rate.

- DVD Recordable / Rewritable reading Tests

The chart below shows the Nero CDSpeed average reading speed results with the following media:

• 8x DVD+R
• 4x DVD+RW

• 4x DVD-R
• 4x DVD-RW

The BTC drive was only marginally faster than the TDK with DVD+/-R media, and was the slowest with DVD+/-RW media. The best speeds here came from the Toshiba drive.
